70 VIRGINIS B

• Is an extrasolar planet and is 60 light years away in the constellation of Virgo

• 70 Virginis b was considered to be with in the stars habitable zone

• The planet orbit is in the habitable zone and it was nicknamed Goldilocks (not too hot, not too cold)

70 Virginis B is located between galaxy M33 and galaxy M31

KEPLER 22B

• Kepler 22 b was found by a group of American and British scientists when they were being filmed on a documentary on alien planets like Earth

• Their satellite sensed that there was water and a bit of land so they thought it might be suitable for aliens or other species of animals to live
