Question

And according to physics, Earth orbits faster when it is nearer the sun than when it is farther. Does this, in any way, affect the length of day in the earth?

Answer 1

Answer:

Kepler's second law

Explanation:

This is because Kepler's second law says that on its orbit, a planet will sweep equal areas in equal amounts of time. This means that when the Earth is closer to the Sun (which happens in early January, about two weeks after the northern winter solstice) it's moving faster than when it is farther away.
