| Apart from the sun, our own star, the nearest star to us is Proxima Centauri, 4.2 light years away. |
| Anglada-Escudé and his colleagues estimate that Proxima b is at least 1.3 times as big as Earth and is most likely a terrestrial planet, with a surface. |
| This is about the same distance that we are from Proxima Centauri, the nearest star beyond the sun. |
| Proxima Centauri, the nearest star to the Sun at four light years away, is a red dwarf and is too dim to be seen without a telescope. |
| It is part of a triple system consisting of a pair of Sun-like stars, Alpha Centauri A and B, and a more distant and faint red companion, Proxima Centauri. |
| The cloud is nearly a light year from the sun, a quarter of the distance to our nearest neighbouring star, Proxima Centauri. |
