Verified Answer
Consider the following statements: 1. Mercury takes the shortest time...
  • Mercury takes the shortest time to revolve around the Sun (88 days) but not for rotation.
  • Jupiter takes the shortest time for rotation. Earth takes 23 h 56 m and 4s to complete one spin and Mars takes 24h and 40m to spin on its axis. So, one Martian day is almost the same as one Earth day.

Consider the following statements: 1. Mercury takes the shortest time...
Explanation:
1. Mercury takes the shortest time to rotate and revolve around the Sun:
- Mercury takes about 59 Earth days to complete one rotation on its axis, making it the planet with the slowest rotation.
- However, it only takes about 88 Earth days to complete one orbit around the Sun, making it the planet with the shortest year.
- This unique combination of slow rotation and fast revolution results in days on Mercury being longer than its years.
2. One Martian day is roughly the same as a day on Earth:
- A day on Mars, also known as a "sol," is only slightly longer than a day on Earth.
- A Martian day lasts about 24 hours and 39 minutes, making it very similar to a day on Earth which lasts about 24 hours.
- This similarity in day length makes it easier for scientists and astronauts to adjust to the Martian day-night cycle.
Therefore, statement 2 is correct while statement 1 is incorrect. Hence, the correct answer is option 'B' - 2 only.
