Mercury's Time Warp Mercury spins extremely slowly on its axis. One Mercury day equals 176 Earth days. But Mercury orbits the Sun in just 88 days. The planet's year is shorter than its day. Sunrise to sunrise takes twice as long as orbiting. Mercury experiences only 1.5 days per year. Time moves differently on the closest planet to our Sun.
