The Earth probably compares in orbital speed to other planets because;

A. The Earth moves faster than the planets that are farther from the sun.

This is because Kepler's second law says that on its orbit, a planet will sweep equal areas in equal amounts of time.

Thus means that when the Earth is closer to the Sun, it's moving faster than when it is farther away.
