Questions:
1. This Jovian moon is the most geologically active planetary body in the Solar System, rendering life on this body very unlikely – but not impossible, especially since all that activity keeps it quite warm. Name this moon.
2. Data collected in 2015-2018 suggested the Solar System’s largest asteroid may have a large subsurface ocean of water, but the evidence is weak. Very salty water is still expected to flow to its surface and may contain microbial life. Name this asteroid.
