● Explain the differences in planet sizes.

The sizes of planets in our solar system vary greatly, with some being relatively small and others being very large. The largest planet in our solar system is Jupiter, which has a diameter of about 86,881 miles. This makes Jupiter more than 11 times the size of Earth.

Other large planets in our solar system include Saturn, Uranus, and Neptune, all of which have diameters that are significantly larger than Earth's. However, when compared to Jupiter, these planets are still much smaller in size.

On the other end of the spectrum, we have smaller planets like Mercury and Mars, which have diameters that are smaller than Earth's. Mercury, for example, has a diameter of about 3,032 miles, making it significantly smaller than Earth.

The smallest planet in our solar system is Pluto, which was reclassified as a dwarf planet in 2006. Pluto has a diameter of about 1,471 miles, making it much smaller than the other planets in our solar system.

Overall, the sizes of planets in our solar system span a wide range, with some planets being significantly larger or smaller than others.
