One interesting result revealed in the new data is the large number of faint red dwarf stars.
ENGADGET: 9-gigapixel image of the Milky Way reminds us just how small we truly are
The surface of these planets would be quite different, due to the light from the red dwarf.
FORBES: No, Scientists Did Not Find 10 Billion Earth-Like Planets In The Galaxy
Grogan, who appeared in shows such as Red Dwarf and EastEnders, will play the mother of Glasgow gangster in The Wee Man.
Cox also took time to appear on British television in this period, appearing in episodes of sci-fi comedy Red Dwarf and Inspector Morse.
Indeed Gliese 581d's parent is a red dwarf the tiniest stellar species.
An analysis of small, dim "red dwarf" stars - which make up a majority of stars in our galaxy - shows that 6% of them host such a planet.

The new deal means that users of the software will be able to download high-quality versions of BBC programmes, including Red Dwarf, Doctor Who and the League of Gentleman.

The small size of the red dwarf stars, typically with spectral types K and M, gives a greater relative drop in brightness when low-mass planets pass in front of them, making it easier to search for planets around them.

"To our complete surprise, we found several red dwarf binaries with orbital periods significantly shorter than the 5-hour cut-off found for sun-like stars, something previously thought to be impossible, " the study's lead author Bas Nefs, from Leiden Observatory in the Netherlands, said in a statement.

By running repeated computer simulations, he has worked out what would happen if a red-dwarf star were to pass through the solar system.
Now, an international team of astronomers has trained the Fermi space-based gamma ray telescope on V407 Cygni, a "binary" system comprising a white dwarf star and a red giant companion, 9, 000 light-years away.
Standard Type Ia supernovae are binary systems in which a white dwarf star draws so much matter from its companion (often a red giant) that it undergoes a kind of energy overload and detonates.
