How do planets stay in their orbits yet not get sucked in to the Sun?

Gravity and inertia both contribute to their orbits. Inertia tends to move a planet away from the Sun, while the Sun's gravity tries to pull the planet closer. Without one of them, a planet would either float away from the Sun (inertia only) or burn up from the Sun (gravity only).

How do planets stay on orbit?
The gravity of the Sun keeps the planets in their orbits. They stay in their orbits because there is no other force in the Solar System which can stop them.
Why do the planets stay in there orbits as they revolve around the sun?
because of the gravity the sun has and also the planets have gravity turning around the sun
Why do planets stay in orbits as they revolve around the sun?

What forces cause the planets to go around the sun and stay in their orbits?
gravity
Why do the planets and the other objects in the solar system stay in their orbits?
The planets and other objects in the solar system stay in their orbits due to the mutual gravitational attraction between each orbiting object and the Sun.
What are the planets orbits?
The planets orbits are the routes or paths that the planets follow around our sun. One orbit is one trip around the sun (one year).
Does the sun orbit the planets?
No. The planets orbit the Sun and the Sun orbits itself.
Why do different planets have different length orbits?
Different planets have different orbit lengths because of their distance from the sun. Planets closer to the sun have shorter orbits, and planets farther away have longer orbits.
How are planets kept in their orbits as they revolve around the sun?
All the planets stay in orbit around the sun because of the sun's gravitational pull. Now you are probably wondering why the planets don't all get sucked into the sun,well it is the high orbital speed that keeps the planets from falling all the way into the Sun and since there is no friction in the vacuum of space, that speed doesn't slow down.
What evidence do you have that the planets move in elliptical orbits around the sun and not in circular orbits?
Elliptical orbits of the planets around the sun actually match what we observe. Newton's Theory of Universal Gravitation states that planets will move around the sun in elliptical orbits.
Which object's gravity holds the planets in their orbits?
The sun's gravity holds the planets in their orbits. It also holds other space objects in their orbits, such as asteroids.
Why do planets in the solar system remain in circular orbits around the sun?
Because the sun is the biggest thing in our universe, so it has the largest gravitational pull on other objects. Once that object gets into the sun's gravitational pull, the object will orbit the sun. Just like the planets. I know, IT IS A HARD CONCEPT TO GRASP!!!!!!!!!!!!!!!!!!!!
