Well, in April last year the Kepler Space Telescope discovered a planet outside of our solar system. So far, it seems to resemble our home planet more than any other yet found!
It orbits on a red-dwarf star from the outer edge amid so-called habitable zone. The ring-shaped region around a star where liquid water could theoretically be present on its surface.
However, being in that region doesn't mean that this new world actually is habitable. For example, both Venus and Mars are in the habitable zone of our Sun. And trust me you do not want to spend your vacation at either one of those places.
Astronomers have learned some important basics about Kepler 186F.
- This exoplanet orbits its star once every 130 days.
- It get as much energy from its star as Earth gets from our Sun.
Still, an impressive discovery, right?
