Retro Space Poster-The Gravity Of A Super Earth Keychain
Twice as big in volume as the Earth, HD 40307g straddles the line between Super-Earth and mini-Neptune. Scientists aren't sure if it has a rocky surface or one that's buried beneath thick layers of gas and ice. One thing is certain though: at eight time the Earth's mass, its gravitational pull is much, much stronger.
