About Psi - The Great Blue Hypergiant

Psi is a star located 1,550 light-years away from Earth. It is a blue hypergiant consisting of 15 planets and is the largest star in the universe. It formed from an extremely large super nebula about 10,000 years ago, and the nebula helped form this extremely massive star and its large amount of planets. The star is expected to gradually cool down to a white hypergiant in about 50,000 years from now, yellow in 200,000 years, and red in 2 million years from now. In about 40 million years, the star is expected to go hypernova and will be visible from the naked eye during daylight on Earth. The hypernova will probably cover a large portion of the Milky Way and after the star goes nova, it is expected to turn into a large, potentially supermassive black hole, completely obliterating every single planet and their remains. The star consists of 8 rocky planets (three of them being habitable), and the others are gas giants with one of them being a brown dwarf. It's habitable zone is estimated to be about 70 astronomical units away. The star's total size is estimated to be about 4,000 times that of the Sun with a radius of 15 astronomical units. If placed at the center of the solar system, it would go past the orbit of Uranus. Psi is located in the constellation Canis Major, the same constellation the real-life largest star, VY Canis Majoris is located in, and is visible to the naked eye even in light-pollution environments.

List of planets

Vulcan (Molten Planet)

Vulcan is a molten hot rocky planet located very close to the star's surface. It is almost completely covered with lava, with unusually hot 34,000 F blue lava covering 50% of the surface, 10,000 F yellow lava covering 30% and regular 2,000 F red lava covering the rest of the surface. Due to the closeness of the planet, it is producing a long tail of gas behind it and should melt into the star's gravitational pull within the next several thousand years.
