Super Earth Gravity retro space tourism Poster
- from our Affiliates
This poster imagines a future when we have achieved our vision of human space exploration. Twice as big in volume as the Earth, HD 40307g sits somewhere between a "Super-Earth" and a "mini-Neptune". Astromenrs aren't sure if it has a rocky surface or one that's buried beneath thick layers of gas and ice. It's around eight times the mass of Earth, so its gravitational pull is a lot stronger. It's a wonderful, retro-style vacation advert in an art-nouveau tradition. Image credit: NASA Exoplanet Exploration Program Office
