With an apparent brightness of 1. Its distance to the earth is 33 light years, which makes it one of the closer stars of the solar environment. Furthermore Pollux shines orange to red with the spectral class K0 and is therefore 32 times brighter than the sun. Pollux has only three times more mass than the Sunwhich makes its density very low, which is called the red vacuum. In addition, the surface temperature of Pollux is 4, Kelvin, which is very low in contrast to the sun. Since Pollux is nine times larger than the Sun, it is seen as a red giant.
So he has reached the end of his life and will end up as a white dwarf.
The history of the star: Pollux
Due to the high brightness of the star Pollux it can be found quickly in the night sky. Especially in winter and spring you can see it well in the constellation of Gemini. Furthermore it is very easy to find it under consideration of the winter hexagon. Pollux can be recognized particularly well because it is located in the close vicinity of Castor.

Visibility of Pollux Due to the high brightness of the star Pollux it can be found quickly in the night sky.Pollux is a star that lies in the constellation Gemini. Along with Castor, Pollux is one of the two main guideposts for the asterism, which is sometimes nicknamed "the twins.
The star is a red giant that has finished fusing hydrogen in its core and is now fusing other lighter elements into heavier ones. The star has a temperature of 8, F 4, C. Recently, astronomers discovered that the star has an extrasolar planet, or exoplanet.Saumur puy notre dame 2014
At the time of the discovery publication inscientists estimated it has a mass at least 2. The giant star lies close to Earth, about 35 light-years away, with a luminosity of about 32 times that of the sun, according to NASA.
Its apparent magnitude is 1. Unusually, the star is the brightest in the constellation Gemini but is designated Beta Geminorum; Castorwhich is a little fainter, is Alpha Geminorum. Pollux is a Greek name, but the legend behind the name comes from both Greek and Latin cultures. Pollux and Castor were twins who were supposed to assist sailors in trouble. Together, the twins were called the Dioscuri in Greek and the Gemini in Latin.
The plane was planned to execute test maneuvers that year and to get to a top re-entry speed of Mach 1. Inastronomers published a paper confirming the existence of a planet orbiting Pollux. According to NASA, two teams independently discovered the planet using the "Doppler method," or watching the gravitational wobbles in Pollux that the planet produced. The planet known as Beta Genorium b is much larger than Earth — about 1.

Gemini is a constellation high in the winter sky, containing a number of interesting observing targets.The changing of the seasons brings a change in the constellations, slowly nudged from east to west as we continue our journey around the Sun.
Quite simply they are grouped patterns of stars in our night sky. For thousands of years our ancestors looked to the sky, observed and named them after animals, objects and mythological characters. You will need a bit of imagination as you try to identify each one as the constellation often looks nothing like its name! Inthe International Astronomical Union formally recognised 88 constellations that can be identified on the celestial sphere: an imaginary globe that surrounds Earth.
Each constellation can be found using celestial coordinates : right ascension, and declination. Some constellations are visible all year round and never sink below the horizon so you can see them whenever there is a clear sky.
Colder, clearer evenings are perfect for enjoying the winter constellations as well as a few deep-sky objects like galaxiesstar clusters and nebulae found within them.
You can see these beautiful pin-prick patterns of light, hot fiery stars and clouds of dust and gas with your naked eye, using binoculars or a telescope. This short tour highlights a handful of constellations that, with a clear horizon, are easy to spot after UT. Plus, there are a few tips as to what you may find hiding within them. So, wrap up warm, grab this guide and step outside. You can always use a star chart, astronomy app or free software like Stellarium to help you find each object.
If you were to ask any astronomer which winter constellation you should choose to kick off your stargazing journey, the answer will be Orion, the Hunter see picture, above. Composed of dust and gas and located 1, lightyears away, it is a famous nebula for naked-eye observing and perfect for beginners.
If astrophotography is your thing, read our guide on how to photograph the Orion Nebula. This method is known as star-hopping. Located just above this is another cluster called the Pleiades see abovealso known as the Seven Sisters because of the seven stars you can see with the naked eye.
A pair of binoculars will reveal many more of the dimmer stars within each cluster. Continuing with the tour, find Gemini again and sweep your eyes to the north. Visible all year, these constellations hold some surprising targets. Can you make them both out with your eyes alone?
Mizar is brighter, so reach for your binoculars or scope if you struggle to see Alcor. This is not a naked-eye object, but larger telescopes will show the nebula as a blue-green disc.The other Twin, Castoris the mortal one.
Pugilthe Pugilist or boxer of the Two Brothers, and the immortal one as being son of Zeus. As companion of Apollon CastorPollux was Greek Hrakles and Hrakleesdescending to Flamsteed's day as Herculesand degenerating, in early catalogues, into Abrachaleusthat the 17th century Dutch astronomer Caesius derived from the Arabic AbFather, and the Greek word; this being contracted by some to Aracaleusby Dutch scholar Grotius to Iracleusby the 17th century English orientalist Thomas Hyde to Heraclusand by the Italian astronomer Riccioli — to Garacles.
It is one of the lunar stars made use of in navigation; and, in astrology, differed from its companion in portending eminence and renown. This naturally became the dual Al Dhira'an that also was used on the Desert for other similar pairs of stars. Influences of the 5th Arabic Moon Mansion Al Dhira : Favorable for gain and friendship and for lovers, and destroys magistracies. With Moon transiting here: travel and take medicine. Those born on the lunar day will be truthful, generous, cleanly, respectable, handsome, famous and wealthy, fond of service, friendly with painters and sculptors, honorable merchants.
With Moon here at birth native will be devout, quiet, happy, good-tempered, of wrong views, sickly, thirsty and pleased with trifles. Rules granaries and the nose. It has also been suggested that it may represent Apollo and Hercules. Influences: Ptolemy makes the following observations; the stars in the feet of Gemini have an influence similar to that of Mercury, and moderately to that of Venus; the bright stars in the thighs are like Saturn.
It is said to cause trouble and disgrace, sickness, loss of fortune, affliction and danger to the knees. They would banish the arms of war, the trumpet's call, and the gloom of old age: theirs is a life of ease and unfading youth spent in the arms of love.
They also discover paths to the skies, complete a survey of the heavens with numbers and measurements, and outstrip the flight of the stars: nature yields to their genius, which it serves in all things.
So many are the accomplishments of which the Twins are fruitful. It gives a subtle, crafty, spirited, brave, audacious, cruel and rash nature, a love of boxing, dignified malevolence, and is connected with poisons.
Pollux has a strong Martian nature and has the name 'the wicked boy' of the of the sibling Twins. According to its nature, this star is brutal and tyrannical, violent and cruel if in conjunction with the Sun, Moon, Ascendant, MC or with malefics.
Just as Mars has its good sides if the energy it creates is channeled constructively, so Pollux should not always be considered as unhelpful.With an apparent magnitude of 1. Pollux lies at a distance of It is the nearest giant star to the solar system.
Pollux and its neighbour Castor mark the heads of the celestial Twins, represented by the constellation Gemini. The two stars are about 18 light years apart. Even though they are referred to as twins and appear similar in brightness, the two stars are very different.
Pollux, which is slightly closer to us, is a single star, while Castor is a star system consisting of six stars. Pollux is an evolved giant, orange in colour, with the stellar classification K0IIIb.
Pollux is an intermediate mass star, almost twice as massive as the Sun and almost nine times larger. With an estimated temperature of 4, K, it shines with a luminosity 43 times that of the Sun. Pollux is believed to have started its life as a main sequence star of the spectral type A, but eventually spent its supply of hydrogen and evolved into an orange giant.
It will keep getting bigger until it reaches the end of its life cycle. As it is not massive enough to explode as a supernova, Pollux will end its life by expelling its outer layers to form a planetary nebula, leaving behind a compact white dwarf.
Observations carried out from to revealed that Pollux has a weak magnetic field at the surface, one of the weakest magnetic fields ever detected on a star. The field indicates that Pollux used to be an Ap star, a chemically peculiar class A star with overabundances of certain metals, which had a considerably stronger magnetic field than it has now.
An extrasolar planet orbiting Pollux, named Pollux b or Beta Geminorum bwas confirmed in Scientists suspected its presence sincewhen a team at University of Texas at Austin measured precise relative radial velocities for three class K giant stars: Pollux, Arcturus and Aldebaran. They found long-period variations in the relative radial velocity of all three stars a period of days for Polluxtoo long to be a result of radial pulsations.
The team concluded that these variations might be due either to non-radial pulsations, to a surface feature combined with rotation, or to the presence of a substellar companion with a mass 3 to 12 times that of Jupiter. The existence of Pollux b was announced on June 16, American astronomer Artie P.
Hatzes, who had originally published his hypothesis in and also discovered planets orbiting the stars Epsilon Eridani and HDis credited for the discovery. Pollux b has a mass of at least 2.Fixed star Pollux, Beta Geminorumis a 1. On June 16,it was revealed that the Pollux star has an orbiting planet termed Pollux b.
It is about twice the size of Jupiter with an orbit of days. Their Roman equivalents are Apollo and Hercules. Pollux Hercules comes from the Greek Poludeukes, hence he was the Boxer. Pollux was the immortal twin and a skilled Horseman. When Castor was killed in battle, Pollux asked his father Zeus Jupiter that he die to forever be with Castor.
Zeus killed Pollux with a bolt of lightning and placed the twins in heaven as the constellation Gemini. Propus Castor Pollux Procyon Praesepe. Fixed star Pollux is of the nature of Mars violent death, ultimate ruin by folly or pride.
It gives a subtle, crafty, spirited, brave, audacious, cruel and rash nature, a love of boxing, dignified malevolence, and is connected with poisons. It represents Pollux, the immortal one of the twins, famous for his skill in boxing.
Sometimes called Hercules, and symbolically named A Heartless Judge.Kelayakan pilot tudm
Pollux has a nature as that of Mars and has always been considered to portend eminence and renown, but can indicate a cruel, rash nature and a propensity to be connected with poisons. The energy of Mars can be extremely valuable in such areas as war and business and politics. According to its nature, this star is brutal and tyrannical, violent and cruel if in conjunction with the lights, AC or MC or even linked with malefics. Just as Mars has its good sides if the energy it creates is channeled constructively, so Pollux should not always be considered as unhelpful.
The star badly place could manifest that way, not by the native misusing his energy but by others deceiving the native and fate playing him some cruel tricks. Once again, a fixed star conjunction alone is not necessarily responsible. One has to study the structural elements in the entire cosmogram, Configurations such as this conjunction would indicate the need to be careful, but one cannot deduce a violent death as an outcome.
While often tarred with the same brush as Castor in some astrology, it is generally counted a more positive symbol and the underlying reason may be that it is close in spectral class and color to the Sun, and, though having at least five faint companions as seen from Earth, these are in fact far distant beyond it: It is not a binary.
Gemini is said to cause trouble and disgrace, sickness, loss of fortune, affliction and danger to the knees. Astrologers assigned to this constellation guardianship over human hands, arms, and shoulders; while Albumasar held that it portended intense devotion, genius, largeness of mind, goodness, and liberality. Considered the House of Mercury and a fortunate sign.
Chinese astrologers asserted that if this constellation were invaded by Mars, war and a poor harvest would ensue. This is the head of the Phoenix. Associated with beauty, water, navigation at sea, hygiene, cleaning, repairs, and refurbishments. Because of the association of cleanliness with Godliness virtuethis mansion also presides over law and order, moral uprightness and cleansing of moral wrongs.It is the brightest star in Gemini and the closest giant star to the Sun.
Sincethe spectrum of this star has served as one of the stable anchor points by which other stars are classified. Castor and Pollux are the two "heavenly twin" stars giving the constellation Gemini Latin'the twins' its name.
The stars, however, are quite different in detail.List of big stars-from our Sun to UY-Scuti
Castor is a complex sextuple system of hot, bluish-white A-type stars and dim red dwarfs, while Pollux is a single, cooler yellow-orange giant. Originally the planet was designated Pollux b. In July the International Astronomical Union launched a process for giving proper names to certain exoplanets and their host stars. This was because 'Leda' was already attributed to an asteroid and to one of Jupiter's satellites. In the catalogue of stars in the Calendarium of Al Achsasi Al Mouakketthis star was designated Muekher al Dzirawhich was translated into Latin as Posterior Brachiimeaning the end in the paw.
At an apparent visual magnitude of 1. Pollux is 6. Lunar occultations were possible as recently as about years ago.
Parallax measurements by the Hipparcos astrometry satellite   place Pollux at a distance of about The star is larger than the Sun, with about two  times its mass and almost nine times its radius. Evidence for a low level of magnetic activity came from the detection of weak X-ray emission using the ROSAT orbiting telescope. A magnetic field with a strength below 1 Gauss has since been confirmed on the surface of Pollux; one of the weakest fields ever detected on a star.
The presence of this field suggests that Pollux was once an Ap star with a much stronger magnetic field. Since scientists have suspected an extrasolar planet orbiting Pollux,  from measured radial velocity oscillations.
