Which of these planets completes its orbit in a much shorter space of time?
Answer Details
Mercury completes its orbit in a much shorter space of time.
Orbit refers to the path an object takes around another object in space. In our solar system, each planet orbits around the sun. The time it takes for a planet to complete one orbit around the sun is called its orbital period or year.
Mercury is the planet closest to the sun, and it has the shortest orbital period of any planet in our solar system. It completes one orbit around the sun in just 88 Earth days. In comparison, Venus takes 225 days, Earth takes 365 days, Mars takes 687 days, Jupiter takes 12 years, Saturn takes 29 years, Uranus takes 84 years, and Neptune takes 165 years to complete their orbits.
So, Mercury completes its orbit in a much shorter space of time than the other planets listed in the question.
