Sun remains a main-sequence star. [117] 6 billion years 1.4 billion years in the future Sun's habitable zone moves outside of the Earth's orbit, possibly shifting onto Mars's orbit. [120] 7 billion years 2.4 billion years in the future The Milky Way and Andromeda Galaxy begin to collide. Slight chance the Solar System could be captured by ...
Star: In antiquity, it was believed that the Sun and all the planets orbit the Earth. Thus the Sun was categorised as a planet. Following the acceptance of the Copernican model, it was recognized that the planets (including Earth) orbit the Sun, and it was no longer regarded as a planet. Subsequent discoveries show that the Sun is a star. [5 ...

This model posits that, 4.6 billion years ago, the Solar System was formed by the gravitational collapse of a giant molecular cloud spanning several light-years. Many stars, including the Sun, were formed within this collapsing cloud. The gas that formed the Solar System was slightly more massive than the Sun itself.
A super Jupiter has been spotted around a neighboring star by the Webb Space Telescope — and it has a super orbit. ... The planet and star clock in at 3.5 billion years old, 1 billion years ...
The closest well-measured approach was Scholz's Star, which approached to ~ 50,000 AU of the Sun some ~70 thousands years ago, likely passing through the outer Oort cloud. [267] There is a 1% chance every billion years that a star will pass within 100 AU of the Sun, potentially disrupting the Solar System. [268]
8.2 billion years (5.6 Gya): Tau Ceti, nearby yellow star forms: five planets eventually evolve from its planetary nebula, orbiting the star – Tau Ceti e considered planet to have potential life since it orbits the hot inner edge of the star's habitable zone; 8.5 billion years (5.3 Gya): GRB 101225A, the "Christmas Burst", considered the ...
Small, relatively cold, low-mass red dwarfs fuse hydrogen slowly and will remain on the main sequence for hundreds of billions of years or longer, whereas massive, hot O-type stars will leave the main sequence after just a few million years. A mid-sized yellow dwarf star, like the Sun, will remain on the main sequence for about 10 billion years ...
