In astronomical terms, revolution refers to a revolving around an axis outside the object, in this case the solar orbit of a planet - the completion of one period of which is called the planet's year. (Mostly because of axial tilt this also brings about the seasons.) By contrast, the rotation about an axis going through the object (spin) brings about the planet's day.

A planet's revolution around its star causes changes in seasons, temperature variations, and daylight hours. It also affects the distribution of sunlight across the planet's surface, influencing climate patterns and ecosystems.
Planets closer to the Sun, like Mercury and Venus, have shorter revolution periods because they have shorter distances to travel around the Sun. Outer planets, such as Neptune and Pluto, have longer revolution periods due to their larger orbits.
because of the sun
As planets move from outer to inner planets, their periods of revolution decrease. This is because the inner planets are closer to the Sun, so they have shorter orbital paths and complete their revolutions more quickly. Outer planets, being farther from the Sun, take longer to complete their journeys around it.

Planets have revolution times because they orbit around a star like the Sun. This orbital motion creates a year, which is determined by the time it takes for a planet to complete one full orbit around its star. The revolution time varies for each planet depending on its distance from the star and its orbital speed.
