An article being published in the journal “Astronomy & Astrophysics” reports the discovery of two planets with a mass close to that of the Earth around Teegarden’s Star, a tiny star about 12.5 light years from Earth and therefore one of the closest. A team of researchers led by the German University of Göttingen used the CARMENES instrument mounted on the Spanish 3.6-meter telescope of the Calar Alto Observatory, Spain, to conduct one of the recent research focused on small stars.
