Do the densities of the solar system planets fall into two or more groups?

Yes, the densities of the solar system planets can generally be grouped into two categories: terrestrial planets (such as Earth, Venus, Mars, and Mercury) with higher densities due to their rocky compositions, and the gas giant planets (such as Jupiter, Saturn, Uranus, and Neptune) with lower densities due to their gaseous compositions.


Why might the solar wind have a stronger effect on inner planets than on outer planets in the solar system?

The solar wind has a stronger effect on inner planets because they are closer to the Sun and therefore experience higher solar wind densities and stronger solar wind speeds. Outer planets are farther away from the Sun and have weaker solar wind interactions due to the decreased solar wind density and speed at their distance from the Sun.
