True

Answer 1

The statement is false. While planets do travel around the sun, their speed is not constant. According to Kepler's laws of planetary motion, specifically the second law (the law of areas), a planet moves faster when it is closer to the sun in its elliptical orbit and slower when it is farther away. Therefore, the speed of a planet varies throughout its orbit.
