It too has a companion star that will explode in a type 1a blast. In the 1960s, NASA called its two-man-crew space program "Gemini." Most scientists believe that the star will end its life by expelling its outer layers to form a planetary nebula, leaving behind a compact white dwarf. Pollux b was given the proper name Thestias, after Leda, the mother of Castor and Polydeuces in Greek mythology. Like other red giants, this process causes Pollux to become cooler than our Sun hence its orange color and much larger: 10 times the diameter of the Sun. They also had a sister, the famous Helen of Troy. Observational efforts have been mostly directed towards identifying possible observational signatures of the progenitor binary. The 10 brightest stars in Gemini are Pollux (Beta Gem, mag. 3. How does a 1.2-solar-mass white dwarf compare to a 1.-solar-mass white dwarf? It is only slightly fainter than Antares in the constellation Scorpius and Spica in Virgo, and it just outshines Fomalhaut in Piscis Austrinus and Deneb in Cygnus.

A relatively close 34 light-years away, Pollux is just under two times the mass of our sun, almost nine times the diameter of the sun, and about 30 times the suns brightness in visible light. Thus, a supernova is a part of the circle of celestial life. The planet is at 1.6 astronomical units from its star, or 1.6 times the equivalent Earth-sun distance. Sirius A (Alpha Canis Majoris) Our number one star on the list. Mass is how much matter there is in an object. The first happens in a binary star system. This is the weakest ever discovered in a star. Supernova can produce elements like titanium, iron, cobalt and nickel. A supernova explosion is the powerful and catastrophic death of a star. When a star goes supernova, its core implodes, and can either become a neutron star or a black hole, depending on mass. The next star to go supernova could be the seventh brightest star in the sky, Rigel. They had different fathers though, Castor had a mortal father and was thus mortal himself, while Pollux was the son of Zeus and was thus immortal. What stage is Pollux in?

The bright star appearing to the lower left of the Moon will be Pollux. The Hertzsprung-Russell diagram is one of the most important tools in the study of stellar evolution.Developed independently in the early 1900s by Ejnar Hertzsprung and Henry Norris Russell, it plots the temperature of stars against their luminosity (the theoretical HR diagram), or the colour of stars (or spectral type) against their absolute magnitude (the observational HR diagram, also known . Since 1943, the spectrum of this star has served as one of the stable anchor points by which . Will Pollux become a supernova? "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. Type II supernova progenitors include stars with at least 10 solar masses that are in the final stages of their evolution. Probably the best month to observe the constellation is in February this is when it is the most prominent. Pollux is an intermediate mass star, almost twice as massive as the Sun and almost nine times larger. After about a billion years the sun will become hot enough to boil our oceans. Observations by NASAs Hubble Space Telescope show that the unexpected dimming of the supergiant star was most likely caused by hot material ejected into space that formed a dust cloud that blocked starlight coming from Betelgeuses surface.
