Question

How does the Earth probably compare in orbital speed to the other planets?

Question 1 options:

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


B.The Earth moves faster than the planets that are closer to the Sun.


C.The Earth moves at the same speed as all the other planets


D.The Earth moves at a slower speed than all the other planets.

Answer 1

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.
