Also, all the planets spin while they move around the Sun... Just like tops! ... There is another mess of stuff that orbits the Sun... We call it the Asteroid Belt and it is just a bunch of really big rocks.

The table showing the elapsed years/orbits helps give an indication of the orbital period around the Sun, which is related to the planets' orbital speeds and distance from the Sun. The numbers represent the number of orbits each planet makes around the Sun which is equivalent to the number of years on that planet.

The solar system was formed from a rotating cloud of gas and dust which spun around a newly forming star, our sun, at its center. The planets all formed from this spinning disk-shaped cloud, and continued this rotating course around the sun after they were formed. ... The gravity of the sun keeps the planets in their orbits.

The planets move in elliptical orbits with sun at one focus. ... The periods P of the planet's orbits are related to the semimajor axes a of their orbits by ; In fact, Newton found the constant: This relation allows one to measure the masses of the Earth, the Sun, other planets, stars ...

He suggested that Earth and other planets revolve around the Sun. The controversy raged; ... The only force at work here is the gravitational force between the Sun and planets. The orbits have remained stable for billions of years and will continue to stay the same unless some large outside force affects the solar system,
