The sun's gravity keeps them in orbit and prevents them from flying off into space. The planets travel quickly enough that they do not fall into the sun.

Does the sun have a moon?

The sun has 8 or 9 major planets and thousands of smaller objects orbiting around it. Some of the planets have many moons. (eg Neptune has 13) It can have moons but so far all of the moons are to close to the planets to get caught in the sun's orbit.


How many planets are there in the Milky Way?

There were originally 9 planets in our solar system, but now there are only 8 because Pluto is not considered a planet. In the whole of theMilky Way Galaxythere are probably billions of planets.

How do planets move around the solar system?

Objects are attracted to other objects. now this is much more complex than that but I neither have the technical knowledge or time to truly explain all that. So because particles are attracted to each other the more mass an object has the more it pulls or attracts other objects, we call this force gravity. Objects such as planets that are orbiting other things (typically stars due to their massive size) are in a place where the force of gravity is not allowing them to escape but not entirely pulling them in. Stars (like the Sun) and planets form from fast-swirling clouds of dust. When their force of gravity is great enough, the swirls clump together into a spherical ball. That does not make them stop spinning or stop them from orbiting the Sun. We see that there is very little to make the spinning, orbiting planets slow their spins or orbits.


Why is there 8 planets?

In 2006 the international astronomical union changed the definition of what a planet was. This meant that Pluto no longer met the definition of what a classic planet was and it was demoted to a dwarf planet status instead.

Does the sun haves moons?

The Sun has 8 major planets orbiting it, as well as asteroids, meteoroids and comets. However, it can never have a moon because moons are objects that orbit a planet, not a star, like the sun.

What will happen if you don't have sun?

If the sun where to abruptly cease to exist, after 8 minutes, the planets orbiting it would careen off into space. This would be due to the sudden ceaseation of the effect of the sun's gravity, which can only travel at the speed of light.
