Because they are farther away from the sun, and the sun is what they revolve around, so they have a longer distance to go. That obviously makes the day longer on that planet, along with all other time measurements. Some planets take longer to revolve because of their distance to the sun. The further a planet is, the more distance it has to cover and the weaker the sun's gravitational pull is. Planets farther away from the sun move more slowly, and have more distance to cover.

Some planets take longer to revolve around the sun because they are farther away and have a larger orbit. This means they have a greater distance to cover in their journey around the sun, so it takes longer to complete one full revolution. Additionally, the time it takes for a planet to revolve is also influenced by its orbital speed and the gravitational pull of the sun.
Planets farther from the sun have larger orbits, which means they have to travel a greater distance to complete one revolution around the sun. This larger distance results in a longer orbital period compared to planets closer to the sun. It follows Kepler's third law of planetary motion, which states that the square of a planet's orbital period is proportional to the cube of its average distance from the sun.
Outer planets like Jupiter, Saturn, Uranus, and Neptune have larger orbits because they are farther away from the Sun compared to inner planets. This increased distance leads to a longer orbital period, resulting in longer years to complete one full orbit around the Sun.
Planets further out from the sun have a larger orbit to travel around, which takes more time. This is because their orbital path is longer, meaning they move at a slower average speed compared to planets closer to the sun. This results in different orbital periods for different planets.
Outer planets take longer to orbit the sun because their orbits are larger and therefore they have more distance to cover in their journey around the sun, as described by Kepler's third law of planetary motion. Additionally, the gravitational pull of the sun decreases with distance, leading to slower orbital speeds for outer planets compared to inner planets.
Mars does not rotate around the Sun. It revolves around the Sun. It takes Mars about 687 Earth days for Mars to revolve once around the Sun.Planets and moons rotate about their own axes, but they revolve around the Sun (for planets) or (for moons) other planets.
