HD 40307g - Experience the Gravity of a Super Earth - NASA JPL Space Tourism Poster

The Visions of the Future posters, from the NASA's Jet Propulsion Laboratory in California, promote travel to planets and moons. The poster depicts a person with a parachute, skydiving and e
xperiencing the strong gravitational pull of planet HD 40307g. "Twice as big in volume as the Earth, HD 40307g straddles the line between "Super-Earth" and "mini-Neptune" and 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."
