Mercury, a planet in our Solar System, and Callisto, a moon of the planet Jupiter, are about the same size. However, Mercury’s mass is about 3 times greater than Callisto’s mass. Why could a future astronaut (perhaps you!) jump higher on Callisto than on Mercury? Use gravitational ideas to answer this question. Write at least three sentences

pls help no without mfkn links

Callistos mass is less therefore it has less gravity (gravitational force is proportional to mass). Although there the same size it would be t

Explo jump on Callisto. An extreme example of this would be a black hole compared to earth, a black hole as big as the earth would immediatly kill you becuase of its strong gravitational force, whereas earth would pull you much less becuase it is much less massive.

layer a is the exosphere and layer b is the thermosphere.   is the answer i think but i hope this .
