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. 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. The X-ray emission from this star is about 1027 erg s−1, which is roughly the same as the X-ray emission from the Sun. It is also larger than a number of stars with the luminosity class III, including the orange giants Pollux (8.8 R ☉) and Unukalhai (12 R ☉), the yellow giant Capella (11.98 R ☉), and the blue-white giant Hadar (13 R ☉). Fixed star Pollux, Beta Geminorum, is a 1.14 magnitude giant yellow-orange star, located in the head of the Southern Twin of Gemini Constellation. POLLUX STAR. Crepe silk placement printed saree with navy blue silk embroidered blouse. Pollux estimated radius has been calculated as being 7.95 times bigger than the Sun. -0.04 with Visible Power and Brightness. Its apparent magnitude is 1.14, making it the 17th brightest star in the night sky. And Pollux is dwarfed by Arcturus, which is almost 26 times the size of the sun. Pollux, one of the main stars in Gemini, is bright and easy to find in the night sky. POLLUX STAR Zoutelande NL. Pollux is a solitary star, located some 35 light years from us, and is a typical aging orange giant star which has swollen in it's final years to span eleven times the diameter of our sun. Pollux is 33.7 light-years from Earth. Pollux is an intermediate mass star, almost twice as massive as the Sun and almost nine times larger. Please deactivate your ad blocker in order to see our subscription offer. The Planet: Pollux's greatest claim to fame is an orbiting planet, making one of the very few giants with such companions, and the brightest planet-holding star. Together, the twins were called the Dioscuri in Greek and the Gemini in Latin. The star is a red giant that has finished fusing hydrogen in its core and is now fusing other lighter elements into heavier ones. New York, Vega is the brightest star in the constellation Lyra while Pollux is one of the two bright stars in the Gemini constellation. The exoplanet orbits Pollux at a distance of about 1.64 AU in a nearly circular orbit. [9], The abundance is determined by taking the value of [Fe/H] in the table to the power of 10. SKU: NS009 Category: North Star Women. But there are bigger stars yet. At the time of the discovery publication in 2006, scientists estimated it has a mass at least 2.3 times that of Jupiter, with an orbital period of almost 590 days. More recently, scientists found a planet orbiting the star. Pollux is a star that lies in the constellation Gemini. It is ten times bigger than our Sun. And Sirius is dwarfed by Pollux, which is eight times the radius of the sun. 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. Pollux is a Greek name, but the legend behind the name comes from both Greek and Latin cultures. Please refresh the page and try again. It has a mass of 1.86 solar masses and a diameter 8 times the Sun. The only stars in the northern celestial hemisphere brighter than Capella are Arcturus in Boötes constellation and Vega in Lyra.The only other star visible from northern latitudes that is brighter than Capella is Sirius in the southern constellation Canis Major. © Original Size. [31] The star displays small amplitude radial velocity variations, but is not photometrically variable. Pollux has a spectral type of K0III, a surface temperature of 4865° Kelvin and a luminosity 32 times the Sun. Thus Pollux and Castor arent gravitationally bound, but only near each other along our line of sight. [11] The abundance of elements other than hydrogen and helium, what astronomers term the star's metallicity, is uncertain, with estimates ranging from 85% to 155% of the Sun's abundance. Home / North Star Women / POLLUX. But their proximity in our sky makes them easy to spot. Photo Details. POLLUX STAR. In 2006, astronomers published a paper confirming the existence of a planet orbiting Pollux. So about 1/10 of the light of the sun will be blocked out as the moon passes in front of it. Arcturus’ size relative to the Sun, image: Windows to the Universe Uploaded. (See “Fleeing to the M… Place of Photo. The plane was planned to execute test maneuvers that year and to get to a top re-entry speed of Mach 1.2. The presence of this field suggests that Pollux was once an Ap star with a much stronger magnetic field. Pollux is also the brightest star in the constellation. And if you have a news tip, correction or comment, let us know at: community@space.com. The image above shows the uncropped view of Pollux (North is up) through the Takahashi E-180 Astrograph. With an estimated temperature of 4,666 K, it shines with a luminosity 43 times that of the Sun. POLLUX STAR vlissingen. Even though classified as the beta star of Gemini, it is in fact brighter than its twin Castor (α Geminorum). The stars Castor and Pollux are named for the mythological twins. The existence of the planet, Pollux b, was confirmed and announced on June 16, 2006. And now, scientists have discovered that it harbors a secret: a hidden planet, about three times the size of Jupiter. Space is part of Future US Inc, an international media group and leading digital publisher. s−1. [34], Since 1993 scientists have suspected an extrasolar planet orbiting Pollux,[35] from measured radial velocity oscillations. Uploaded. Moon + Mercury 2012-06-21 conjuction and Pollux.jpg 3,160 × 2,107; 787 KB Pollux from 1,6 UA.jpg 645 × 486; 20 KB Pollux-Sun comparison.png 1,009 × 842; 350 KB The planet is at 1.6 astronomical units from its star, or 1.6 times the equivalent Earth-sun distance. The star has a temperature of 8,360 F (4,627 C). The Sun's radius is 695,800km, therefore the star's radius is an estimated 5,529,374.30.km. Size: Clear: POLLUX quantity. Castor is a multiple star system made up of six individual stars; there are three visual components, all of which are spectroscopic binaries.Appearing to the naked eye as a single star, Castor was first recorded as a double star in 1718 by James Pound, but it may have been resolved into at least two sources of light by Cassini as early as 1678.

Arcturus, larger than Pollux, is located 37 light-years away and is about 20 Sun diameters. Its … Original Size. "We want to fly while re-entering, and we want to reduce the logical gap between aeronautics and space," said Gennaro Russo, CIRA's Space Programs lead and unmanned space vehicles program manager in 2010. prototype space plane that it called Pollux, watching the gravitational wobbles in Pollux, planet-formation around stars much more massive than the sun may [be] common, Watch live Saturday: Space station astronauts are taking a spacewalk, China's Long March 7A rocket launches on 1st successful flight. Sirius, the brightest star in the night sky, is twice as massive as the sun and 25 times more luminous. There was a problem. It’s a big, big universe. Castor's location is: Right ascension : 07 hours 34 minutes 36.0 seconds Vega and Pollux: Vega and Pollux are two stars in the Milky Way Galaxy. Photo Details.

Pollux, also called Beta Geminorum, brightest star in the zodiacal constellation Gemini. Plus they are different kinds of stars. Size of the Earth relative to the Sun, comparative sizes of some super giant stars like Antares, Betelgeuse, Rigel, Aldebaran and some white dwarfs as Arcturus, Pollux, Sirius and the Sun. Going by the picture at the bottom, giant stars are say 10x bigger than our own sun such as Pollux, supergiant stars are 100x bigger than ours and hypergiants are 1000x and above. The size of the pollux star is 11.62 millon square kilometers. In 2010, the Italian Center for Aerospace Research (CIRA) had a prototype space plane that it called Pollux. You will receive a verification email shortly. "It suggests that planet-formation around stars much more massive than the sun may [be] common," read an Astronomy and Astrophysics paper concerning the discovery. The planet (known as Beta Genorium b) is much larger than Earth — about 1.6 times the size of Jupiter — and also orbits slightly farther away from Pollux than Earth does from the sun.
