When a Planet moves around the sun it is called an orbit, as it orbits around the sun.
The point of closest approach is called perihelion. Aphelion is the point where the planet is the farthest away.
The geocentric theory was the idea that the sun moved around the planets.
But later it was disproved by the heliocentric theory that we know today.

The outer planets take longer.
When don't they? If a planet is in orbit around a star, it is in continual orbit. Orbital periods (the lengths of time it takes different planets to complete one orbit) are different from planet to planet, and are related to the distances between the planets and their stars.
Different planets have different times to orbit the Sun. Mercury takes 88 days. Uranus takes 84 Earth years.
Saturn orbits the Sun like the other planets, it does not orbit anything else. One orbit for Saturn takes 29.4571 Earth years.
The path a planet takes is called an orbit.The planets are kept in orbit by the gravitational pull of the star (in our case the Sun) they orbit.
Because gravity is stronger as it gets closer to the planet it is orbiting. and orbits are caused by the gravity of the planit they are rotating.
The two closer to the sun than the earth, mercury and Venus. The further you go out from the sun, the longer it takes to orbit it.
The path is called the orbit. There are 8 planets (excluding Pluto and the other dwarf planets) with separate paths at various unique distances from the Sun.The planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune (in order of increasing distance from the Sun).The path that a planet takes while traveling around the sun is called its orbit. Mercury has the fastest orbit, at 88 days. Neptune has the longest orbit, at 165 years.
The path the planets take around the sun, is called a orbit.
Only the earth orbits the sun once a year. Mars orbits the sun once every 2 years. As you get closer to the sun the planets orbit the sun in less than a year. As you get past Mars, it takes even longer.
earth
The satellite that orbits the planet Earth is called Moon, and completes a complete orbit cycle once every 27.32 days. The Moon may appear closer to other planets at times because the path the Moon takes around the Earth is elliptical, meaning more oval then circular.
because the farther a planet is from the sun, the longer it takes to make one orbit
The outer planets take longer.
