Detailed explanation-1: -Planets that orbit closer to the Sun than Earth have shorter years than Earth. Planets that orbit farther from the Sun than Earth have longer years than Earth. This happens for two main reasons. If a planet is close to the Sun, the distance it orbits around the Sun is fairly short.
Detailed explanation-2: -When a planet is closer to the Sun the Sun’s gravitational pull is stronger, so the planet moves faster. When a planet is further away from the sun the Sun’s gravitational pull is weaker, so the planet moves slower in its orbit.
Detailed explanation-3: -It was already known that Venus has the longest day-the time the planet takes for a single rotation on its axis-of any planet in our solar system, though there were discrepancies among previous estimates.
