Why do planets don't fall down?

Answer 1

Actually gravitational influences can be found all over the universe and currently it is thought that gravity never goes out of range but just gets weaker and weaker with distance.

The reason planets don't fall into the Sun is that they have their own velocity.

This, combined with the Sun's gravity, produces a stable orbit around the Sun.

Answer 2

They don't fall into the Sun because their speed is too great to let them fall straight in. The Sun's gravitational attraction only makes them curve towards the Sun as they move in their orbit. The force makes them take up elliptical orbits instead of just shooting away in a straight line.

Answer 3

Planets are in place in the solar system because of the Sun's gravitational attraction and the velocities of the planets. This combination produces a stable orbit around the Sun.

So, things tend to fall in a gravitational field, but other factors can prevent that from happening. The solar system itself revolves around the centre of the Galaxy. It doesn't fall into the centre for the same reason that planets don't fall into the Sun.

The velocity of the solar system keeps it in orbit around the centre.

Answer 4

They are all on their own orbit and different distances from the sun. Since the planets in our solar system are thought to all have stable orbits, they never approach each other closer than a certain distance, a distance that is larger than any distance observable on Earth. In the past, during the formation of our solar system, however, planets did collide with each other. Indeed, it was chaos, as hundreds of small objects, called planetesimals, collided with each other, accreting into larger objects. When enough planetesimals collided to form a body that could attain hydrostatic equilibrium (become round by its gravity), such an object is then called a protoplanet. This process of accretion occurs in practically all solar systems, not just ours. If planets and planet-like objects never bumped or collided, planets the size of Earth or larger would likely never form.

Answer 5

There is no friction in space to slow them down.

Answer 6

They don't. The planets are in constant motion as they orbit the sun.

Answer 7

Planets do not collide because they are orbiting around the sun at different speeds and distances. I hope this helps!
