Answer:
About 88 earth days.
Step-by-step explanation:
It is much closer to the sun than the earth, and therefore has less distance to travel to orbit the sun.
Mercury is the smallest planet of the eight planets and is made up of rock and metal. One year on Mercury is only 88 Earth days. That's how long it takes for Mercury to orbit the sun. Mercury rotates very slowly, so its days are very long. A day on Mercury is 59 Earth days.
