Astronomers Find Two Earth-Like Exoplanets Called from Teegarden b and Teegarden c, they orbit a red dwarf star that is located only 12.5 light-years from our planet.
Astronomers are convinced they have found two new Earth-like planets.
According to a study published in the journal Astronomy & Astrophysics, the similarities are so great that they are among the 19 largest known exoplanets that would have potentially habitable environments for future colonization.
“The two planets resemble the inner planets of our Solar System,” said Mathias Zechmeister, an astrophysicist at the University of Göttingen in Germany.
“They are only slightly heavier than the Earth and are located in the so-called habitable zone, where water may be present in liquid form.” The planets were named Teegarden b and Teegarden c, as they orbit the Teegarden star, a nearby red dwarf located just 12.5 light-years away in the constellation Aries, considered one of the smallest stars ever discovered.
With eight billion years, it was discovered in 2003 it is 10 times lighter than the Sun. “Both planets have a minimum mass near an earth-land mass, and a rocky composition, partly made of iron or water,” the researchers wrote in the study.
This does not mean that the two planets are actually habitable, but scientists consider it a promising sign. Teegarden B completes its orbit in just 4.9 Earth days and has the highest Earth Similarity Index. The Teegarden c completes its orbit in 11.4 Earth days.
