Sticky Note
The planet with the shortest rotation time around its axis is ____?
اپنے محور کے گرد گردش کا سب سے کم وقت والا سیارہ ____ ہے؟
  1. Jupiter
  2. Mars
  3. Earth
  4. None of these
Explanation
  • The question asks for the planet with the shortest rotation period, which means the planet that rotates the fastest.
  • Jupiter is the correct answer as it rotates the fastest among the given options with a period of 9.9 Earth hours.
  • Mercury has a longer rotation period than Jupiter, while Mars has a similar rotation period to Earth.
  • Venus has the slowest rotation period among the given options.

Additional Information

  • Mercury: It has a rotation period of 58.6 Earth days, which is longer than its orbit around the sun.
  • Jupiter: It has a rotation period of 9.9 Earth hours, making it the fastest rotating planet in our solar system.
  • Mars: It has a rotation period of 24.6 Earth hours, which is similar to Earth's rotation period.
  • Venus: It has a rotation period of 243 Earth days, making it the slowest rotating planet in our solar system.
