How close is the nearest star with planets?

Answer 1

Alpha Centauri B has a planet and is 4.35 light years away.

The three stars that make up the Alpha Centaur star system are Alpha Centauri A, Alpha Centauri B, and Proxima Centauri. An exoplanet has been found to be circling Alpha Centauri B.

There has been the discovery of an exoplanet orbiting one of our nearest neighbors, Proxima Centauri, which is the closest star to our solar system at 4.22 light years, while Alpha Centauri A and B are about 4.35 light years away.
