Revolution
The planets of the solar system all revolve around the Sun under the effect of gravitation.
This movement is called the revolution, the period of revolution is the time a planet takes to return to its initial position.
The planet Mercury has a revolution period of 87.969 days, its orbit is inclined by 7° with respect to the ecliptic.
Click on the arrows in the dashboard to increase or decrease the time speed. You can thus see the distance between Mercury and the Sun in real time.

Aphelion and perihelion
The orbits of the planets are not perfectly circular, but elliptical. This means that there is a point closer to the Sun (the perihelion) and a point further away (the aphelion).
