Which star is closest to the Sun?

The closest encounter to the Sun so far predicted is the low-mass orange dwarf star Gliese 710 / HIP 89825 with roughly 60% the mass of the Sun. [ 4 ] It is currently predicted to pass 0.1696±0.0065 ly (10635±500 au) from the Sun in 1.290±0.04 million years from the present, close enough to significantly disturb the Solar System's Oort cloud.

Why is Proxima the closest star to the Sun?

That’s because it’s part of the Alpha Centauri system, the closest star system to our sun. Alpha Centauri consists of three known stars (including Proxima). Of the three, Proxima is closest, at 4.2 light-years away. Alpha Centauri appears as the 3rd-brightest star in Earth’s sky. But Proxima is too faint to see with the eye.

Which star is closest to Alpha Centauri?

Alpha Centauri consists of three known stars (including Proxima). Of the three, Proxima is closest, at 4.2 light-years away. Alpha Centauri appears as the 3rd-brightest star in Earth’s sky. But Proxima is too faint to see with the eye. It’s a small, dim, low-mass star, with its own planetary system.

Which star is closest to the Sun – Proxima Centauri?
