Question

Help I need to know how to do this

Answer 1

Explanation:

Add the diameters of Earth and Mars together and then compare the result to that of Jupiter:

`D_E + D_M = 1.28×10^4 + 6.785×10^3 = 1.96×10^4\:\text{km}`

Jupiter's diameter of
`1.428×10^5\:\text{km}` is much larger than the combined diameters of the Earth and Mars by more than a factor of 7.
