Question

The farther a planet is from the sun, the longer will be its year. For instance, mercury is the closest planet to the sun and hence, has a year of 88 earth days.

Answer 1

Answer:

Because farther planets have larger orbit than smaller planets, so they take more time to revolve around the sun(planets revolve around the sun to make one year).

Answer 2

Answer:

Mercury spins slowly compared to Earth, so one day lasts a long time. Mercury takes 59 Earth days to make one full rotation. But a year on Mercury goes fast. Because it's the closest planet to the sun, it goes around the Sun in just 88 Earth days.
