Question

What is earth's orbital period and rotational period?

Answer 1

orbital period means the period when the earth orbits and rotational means when the earth rotates

Answer 2

Earth rotates once in about 24 hours with respect to the Sun, but once every 23 hours, 56 minutes, and 4 seconds with respect to other, distant, stars (see below). Earth's rotation is slowing slightly with time; thus, a day was shorter in the past. This is due to the tidal effects the Moon has on Earth's rotation.....hope it may help you.....
