Which planet orbits the Sun the fastest?


All the planets revolve around the Sun (yes, Pluto too, but it’s not a planet). But which is the fastest to make a turn in its orbit? Among the many useful little features that came with iOS 16 to the iPhone, the lock screen did not go unnoticed. You can make the solar system appear there, with the position of its stars in real time. Obviously, the movement of the planets that appear on the screen is not noticeable, even if you look at the image for a few moments. In our system, each planet evolves at its own pace around the Sun. But which is the fastest of all in this revolution movement around the star? It’s little Mercury: it loops the fastest orbit around the Sun. It also happens to be the closest planet to the star. Planets revolving around the Sun (objects not to scale). Here are the speeds of revolution of the various planets in the solar system (in kilometers per second and kilometers per hour), and the period of revolution (ie the length of the year for each, in days or Earth years) . Pluto is added to the list, although it is not a planet, but a dwarf planet.

The closer an object is to the star in the solar system, the faster it must go to maintain its orbit. This speed of movement is also not constant. At perihelion, the stars move faster in their orbit: at aphelion, they move more slowly. However, the variations are quite negligible, since the planets in the solar system have nearly circular orbits around the Sun. For comets, on the other hand, the situation is different, because their orbit around the Sun is very eccentric. We see this with the example of Halley’s comet. In 1948, when the comet was at aphelion (well beyond the orbit of Neptune), it was moving at a speed of 0.91 km/s. In 1986, at perihelion (in the orbit of Venus), the comet had a speed of 54.55 km/s.
