", is co-written with astronaut Dave Williams. Pollux shines 48 times brighter than our sun 48 solar luminosities, being the brightest star in its constellation. It has exhausted the hydrogen in its core to become a white supergiant and no longer fuses hydrogen. The star collapses by its own gravity and the iron core heats up. Moving onward, we have IK Pegasus, one of two stars in an ill-fated binary system. Astronomy vs. Astrology: What Is the Difference. 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 were the sons of the Spartan Queen Leda, wife of Tyndareus, and brothers of Helen of Troy and Clytemnestra, wife of Agamemnon, king of Mycenae. Cataclysmic Variables as Supernova Ia Progenitors - type Ia supernova progenitors;cataclysmic variables;circumstellar material. If youve ever looked up on a clear winter night, youve probably seen it: Pollux, also known as Beta Geminorum, one of the brightest and most familiar stars in the night sky. But the Earth will become uninhabitable much sooner than that. In truth, it's a little difficult to saywhich star will be the first to go; however, we have a few candidates to consider. Can Pollux become a supernova? This is simply a big ball of neutrons, packed very tightly together by gravity. Pollux along with Castor, are the two main guideposts for the asterism nicknamed the Twins. A supernova is a star at the end of its "life." It goes out with a bang! 33.78 0.09 light years (10.36 0.03 parsecs), Pollux, Beta Geminorum, Gem, 78 Geminorum, HD 62509, HR 2990, HIP 37826, GC 10438, LHS 1945, SAO 79666, GCTP 1826.00, LFT 548, LTT 12065, BD+281463, PPM 97924, CCDM J07454+2802A, FK5 295, GCRV 5166, GJ 286, IRAS 07422+2808, TYC 1920-2194-1, WDS J07453+2802A.

The Jellyfish Nebula (IC 443) is a supernova remnant that can be seen at Castors foot, between Tejat and Propus (Mu and Eta Geminorum) and not far from the Monkey Head Nebula (NGC 2174) in the constellation Orion. This is because a type II supernova blasts from a star this massive would have a peak luminosity over one billion times the energy produced by the Sun. In a battle, Castor supposedly died and Pollux begged Zeus to let him die and be reunited with his brother. The stars with the longest lifetimes are red dwarfs; some may be nearly as old as the universe itself. https://upload.wikimedia.org/wikipedia/commons/thumb/6/61/Pollux-Sun_comparison.png/575px-Pollux-Sun_comparison.png, https://en.es-static.us/upl/2009/06/gemni_twins-bayer.jpeg, https://en.es-static.us/upl/2009/06/sun-sirus-pollux-arcturus.jpeg, https://s22380.pcdn.co/wp-content/uploads/Gemini-and-Procyon-Fujii_550px.jpg, https://upload.wikimedia.org/wikipedia/commons/thumb/b/bf/Gemini_constellation_map.svg/865px-Gemini_constellation_map.svg.png.
