Mercury travels around the sun at the lowest speed compared to other planets in our solar system. Its average orbital speed is about 47.87 km/s.
Orbital velocity refers to the speed at which a planet travels in its orbit.
Mercury is the closest known planet to the sun, in terms of its average orbital distance. It's also the one with the highest speed in its orbit, and the one with the shortest period of revolution or 'year'.Mercury's average distance from the sun: 36 million miles (58 million km)Average orbital speed: 29.7 miles (47.9 km) per secondPeriod of revolution around the sun: 88 earth days
According to Kepler's Third Law, the planets that are nearer to the Sun movefaster than the planets that are farther away. The closest planet - and thus thefastest - is Mercury; the farthest planet from the Sun is Neptune.==================================The way gravity works guarantees, that the closer an object is to the sun, the faster it moves, whether the orbit is almost circular or highly eccentric. This simplerule instantly lines up the speeds of the various solar system objects for us:Fastest speed:Comets which, at their closest approach, spend part of their time inside the orbit of Mercury.Their speed is highest when they're closest to the sun.Known planet with the highest average speed:The planet nearest the sun . . .

The speed of a planet revolving around the Sun is slowest at the aphelion, which is the point in its orbit farthest from the Sun.

The latitude closest to the equator travels at the fastest speed because its rotational velocity is highest due to the Earth's rotation. As you move towards the poles, the rotational speed decreases.
The orbital speed of the Earth around the Sun averages about 108,000 km/h. The planet travels a total of 940 million kilometers in one revolution.
The orbital speed of a planet is the time it takes to cycle around the sun. The spinning speed of a planet is the time it takes for the planet to rotate on it's axis.

The speed of a planet revolving around the Sun is slowest at the aphelion, which is the point in its orbit farthest from the Sun.
The planet with the highest rotational speed in our solar system is Jupiter, with a period just under ten hours.
