Which planet experiences a day almost of the same duration as that of the Earth?

Last updated Sep 22, 2026

Correct Answer: Option A — Mars

Because their rotation periods and axial tilts are so similar (Earth is at 23.5° and Mars is at 25°), Mars experiences seasonal cycles and day-night patterns that are remarkably similar to those on Earth. A day on Mars is often referred to by astronomers and space agencies as a "Sol."
