The star's effective temperature is 10,286 Kelvin which is hotter than our own Sun's effective Temperature which is 5,777 Kelvin. What is the novel strategy to popularize environmental causes was introduced in 2008. Pollux – β Geminorum (Beta Geminorum) Pollux is the brightest star in Gemini and the 17th brightest star in the night sky. Star with planet.In northern spring evenings, the "twin" stars Castor and Pollux of the constellation Gemini descend the northwestern sky looking like a pair of eyes staring down at the Earth. Pollux or Beta Geminorum (Bet Gem) is the brightest naked eye star in the constellation Gemini.With an apparent magnitude of 1.16, Pollux is the 17th brightest star in the entire sky (see: 50 Brightest Stars ).Its absolute magnitude is 1.09 and its distance is 33.7 light years.The Equinox J2000 equatorial coordinates are RA = 07h 45m 18.9s, Dec = +28° 01' 34". Castor Luminosity The surface temperature of the Pollux star is 4,500 K Is Matt le Blanc related to Gordon Macrae. Asked in Betelgeuse

The “b” indicates that the star is less luminous than average for its class. Both Betelgeuse and Pollux are close to the end of their life. In 2006, astronomers discovered a planet orbiting Pollux; they named it Thestias . Castor Colour and Temperature . It has an apparent magnitude of 1.14 and is 33.78 light years distant from the solar system. Pollux An orange giant star which lies around 34 light years from Earth, it is around nine times larger than the sun with twice its mass, Pollux is the brightest star in the Gemini constellation and is also known as Beta Geminorum. Stellar classification, scheme for assigning stars to types according to their temperatures as estimated from their spectra. 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.Even though classified as the beta star of Gemini, it is in fact brighter than its twin Castor (α Geminorum).. On June 16, 2006, it was revealed that the Pollux star has an orbiting planet termed Pollux b. Both of the stars are large and cold in surface temperature.

One difference is that Betelgeuse is a red supergiant, and Pollux is an orange giant. Based on the star's spectral type of A2Vm , Castor's colour and type is blue - white main sequence star. However, contrary to convention, Pollux bears the designation Beta Geminorum, which by rights should apply to Castor (Alpha Geminorum), which is the second brightest star in Gemini, and only the 23rd brightest star in the night sky. Pollux is a giant orange K star that makes an interesting color contrast with its white "twin," Castor.Evidence has been found for a a hot, outer, magnetically-supported corona around Pollux, and the star is known to be an X-ray emitter. Hot and blue stars have smaller and negative values of B-V than the cooler and redder stars.
Pollux (Beta Geminorum) is the brightest star in the constellation Gemini (despite its Beta designation), and the 17th brightest in the sky.
Pollux .

Pollux is a giant orange K star that makes an interesting color contrast with its white "twin," Castor.Evidence has been found for a a hot, outer, magnetically-supported corona around Pollux, and the star is known to be an X-ray emitter. Pollux is an evolved giant, orange in colour, with the stellar classification K0IIIb. Bellatrix is a massive star with about 8.6 times the Sun's mass.It has an estimated age of approximately 25 million years—old enough for a star of this mass to consume the hydrogen at its core and begin to evolve away from the main sequence into a giant star. Castor is a bright star in the constellation Gemini that, along with Pollux, is one of the two main guideposts for the asterism that is sometimes nicknamed "The Twins.". Pollux (Beta Geminorum) is the brightest star in the constellation Gemini (despite its Beta designation), and the 17th brightest in the sky. Both of the stars are large and cold in surface temperature. ... Its temperature is around 4865 Kelvin and it has a luminosity of 32 times that of our own sun. Polaris is a three star system comprising of the supergiant Polaris A and two smaller companions. Castor's intimate mythological and celestial association with Pollux commonly sometimes lofts it into the "first magnitude" category, though in fact it is the brightest of the second magnitude stars (1.58), coming in just behind Adhara in Canis Major. Pollux is the brightest star in the constellation Gemini, and the 17th brightest in the entire night sky. Castor or Alpha Geminorum (Alp Gem) is the 2nd brightest naked eye star in the constellation Gemini.With an apparent magnitude of 1.58c, Castor is the 23rd brightest star in the entire sky (see: 50 Brightest Stars ).Its absolute magnitude is 0.59 and its distance is 52 light years.The Equinox J2000 equatorial coordinates are RA = 07h 34m 36.0s, Dec = +31° 53' 18".
