The Closest Exoplanet to Earth May Have Neighbors

Astronomers have found a dusty ring around Proxima Centari, which might mean Proxima b isn’t the only planet orbiting the red dwarf star that lies 4.2 light years from Earth.

This image of the sky around the bright binary star Alpha Centauri AB also shows the much fainter red dwarf star, Proxima Centauri, the closest star to our own solar system. The photo was created from pictures forming part of the Digitized Sky Survey 2. The blue halo around Alpha Centauri AB is an artifact of the photographic process; the binary is really pale yellow in color, like the sun. | Digitized Sky Survey 2; Davide De Martin/Mahdi Zamani
