Mars-like extrasolar planet discovered

news-exoplanet-5 mars

Astronomers have identified a planet the size of Mars orbiting a star 200 light years from the Earth.
One of the smallest extrasolar planets ever discovered, this tiny distant world orbits the red dwarf star Kepler-138 and is also thought to have two neighboring planets around the size of the Earth.
Due to its size and distance its discovery is equivalent to locating a pin as far away as the moon.
“We’ve been able to tease out both the size and mass of this planet,” said Dr Jason Rowe of the SETI Institute. “Therefore, we know its average density, and find that it is consistent with Mars in our own solar system.”
