Because each planet is a different distance away from the sun. The farther away from the sun, the longer and wider it's orbital path is, therefore the longer it will take to complete one complete orbit around the sun.
Around its axis is a day. Around its orbit is a year.
One complete orbit of a planet around the sun is called a revolution.
No, the rotation of a planet on it's axis, or it's spin is not really related to the time it takes to orbit or revolve around the sun. For example, Mercury and Venus are the closest planets to the sun, yet they take a long time to rotate on their axis.
Mercury has the fastest revolution around the sun, taking around 88 Earth days to complete one orbit.
To find the number of revolution days of a planet, you can use the formula: revolution days = orbital period / rotation period. The orbital period is how long it takes for the planet to complete one orbit around the sun, while the rotation period is how long it takes for the planet to rotate on its axis. This formula will give you the number of days it takes for the planet to complete one full rotation around its axis.
A revolution is the period it takes for the planet to revolve one time around the sun. Its otherwise known as the planet's year.
One complete revolution of a planet around the sun equals one year.
revolution
The Earth completes one revolution around the Sun ina year.(The orbital period of a planet is known as its year, and each planet requires a different period of time to complete a revolution around the Sun. Some take many Earth years.)
Around its axis is a day. Around its orbit is a year.

Period of rotation
No, the rotation of a planet on it's axis, or it's spin is not really related to the time it takes to orbit or revolve around the sun. For example, Mercury and Venus are the closest planets to the sun, yet they take a long time to rotate on their axis.
Mercury has the fastest revolution around the sun, taking around 88 Earth days to complete one orbit.
Venus
The period of a planet's revolution is the time that it takes to complete one revolution around its axis of rotation relative to the background stars (also known as rotation period).
