Low gravity aliens. Artwork of life forms on a planet with low surface gravity. A rocky planet that is smaller than the Earth would have lower surface gravity. Such a planet would have a thinner atmosphere and would be cooler as a result. Plants may grow to heights far in excess of those on Earth and animals that feed on them also grow tall. In order to sustain life,a smaller Earth- like planet must not have less than one-half of the surface gravity of Earth. Any less and the atmosphere would escape into space. This is the process that many believed occurred on the planet Mars | |
