All of them
The Earth travels around the Sun.
You might be thinking of Pluto, a dwarf planet, orbits the sun every 247.68 years. Pluto, however, is not a planet.
Planets have elliptical orbits around the sun.
The curved path of a planet around the sun is called an orbit. Orbits are elliptical in shape, with the sun located at one of the foci of the ellipse. The gravitational pull of the sun keeps the planet in its orbit as it travels around the sun.
Kepler's third law of planetary motion states that the time taken for a planet to revolve around the sun (or its period) is proportional to its distance from the sun. Therefore the closer the planet is to the sun, the faster its orbit. So the answer is: the closest planet to the sun which is......Mercury.
An orbit.
The planet mercury orbits closest to the sun.
An orbit is the path followed by a planet as it travels regularly round the Sun. The Earth follows an orbit and completes one journey round its orbit in a year.
Every planet in our solar system travels around the sun on its orbit which is a invisible path that goes right around the sun. feel free to add anything
Planets go faster if they are closer to the Sun. No only does the closest, Mercury, get round in the shortest time, it also travels at the fastest speed. The explanation lies in Kepler's laws of planetary motion.
A satellite.
The dwarf planet Pluto. No "planet" takes that time.
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 . . . Mercury.Known planet with the lowest average speed:The planet farthest from the sun . . . Neptune.Known dwarf-planet-like objects with the lowest average speed:Known objects farthest from the sun . . . Pluto, Eris.
An elliptical orbit round the Sun.
haha
Its orbit.
