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.

Solar System Facts

The order and arrangement of the planets and other bodies in our solar system is due to the way the solar system formed.
