Disc around Proxima Centauri, illustration
Numéro d’image : 12422620
| Disc around Proxima Centauri, illustration. The closest star to the Sun, Proxima Centauri, has been found to harbour a belt of dust. Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile detected emissions from a dust belt around the small star. It is similar to the asteroid belt in our own solar system, with particles ranging in size from sub-millimetre dust to asteroids kilometers across. The belt of cool dust is one to four times as far from Proxima Centauri as the Earth is from the sun. The belt is in addition to the planet already found orbiting Proxima. There may be others. | |
