IS EARTH ALONE ?
HD 40307 G
Is an exoplanet in the habitable zone of the star HD 40307
It was discovered by European Southern Observatory’s HARPS apparatus
It is located 42 light years away in the direction of the constellation Pictor

HD 85512 B
• It is an exoplanet classified as a super Earth
• It orbits the star HD 85512 and is at least 3.6 times the size of Earth
• One of the smallest planets discovered to be on the edge of the habitable zone

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

KEPLER 186 F
Is an exoplanet located 500 light years away from Earth
First planet to be discovered to be having almost the same radius as Earth
It is in the habitable zone (Goldilocks Zone)
Takes 129.9 days to orbit its star Kepler 186
It is in the constellation Cygnus
Kepler 186 F
Kepler 62eThis planet is a super Earth in the constellation Lyra and is 60 percent bigger than earth
62e orbits it star Kepler 62 (KOI 701) in roughly 122 days
It Is located 1200 LIGHT YEARS from Earth Size comparison

Gliese 667Cc (GJ-667CcHR-6426Cc)
Is 4.39 masses of the earth is an exoplanet in the constellation Scorpius
Is 22.7 light years away from the Earth
It is in the habitable zone
667Cc is 85 % similar to the Earth
This planet also was discovered by the HARPS apparatus
This planet orbits the star Gliese 667c

Kepler 69cThis planet is a super Earth that lies in the habitable zone and is a meso planet
This planet orbits the star Kepler 69
It is 1.7 times the size of Earth
This planet lies within the constellation Cygnus
