A)about the same as Jupiter's density.
B)similar to the density of water.
C)less than the density of any jovian planet in our solar system.

E)greater than the density of any terrestrial planet in our solar system.

Question

Quizplus · Accepted Answer

Asteroids studied by spacecraft have densities that are less than the density of any terrestrial planet in our solar system. This is because asteroids are small and rocky, and have not undergone the same processes of differentiation as larger planets like Earth. Thus, they have lower densities. Asteroids studied by spacecraft have densities that are less than the density of any terrestrial planet in our solar system. This is because asteroids are made up of rock and metal and are much smaller than planets, so they have less gravitational force to compress their materials into a denser form.
