Who determined the force that kept planets in orbit?
It was Isaac Newton who figured out that the force of gravity keeps planets in orbit around the sun.
What keeps planets in elliptical orbits?
Gravity and velocity (inertia) keeps planets in orbit around suns.
What keeps all of the planets in its orbit?
Gravitational attraction to the sun
What keeps the planets stay in their own orbit?
Gravity - from the sun.
How does gravity help planets and stars and solar system?
it keeps it in orbit
Who determined the force that kept planets in orbit?
It was Isaac Newton who figured out that the force of gravity keeps planets in orbit around the sun.
Did newton discovered that the balance between gravity and keeps the planets in the orbit?
yes he did
What was the name of the scientist who showed that gravity keeps planets and moons in orbit?
Isaac Newton
Who used math to show that gravity keeps planets in orbit around the sun?
Isaac Newton.
What natural forces and law that keeps the planets in their orbit?
Gravitational forces as described by Newton's Universal Law of Gravitation. Also important is the inertia of the planets and Newton's First Law of Motion is involved there.
What keeps the planets in orbit about the sun?
The Sun has a powerful gravitational pull. This, combined with the velocities of the planets, keeps the planets in orbit.
What is the force that keeps planet in orbit?
the suns gravity keeps the planets in orbit
What does gravity have to do with planets?
It keeps them in orbit.
Who explained why planets stay in their orbit?
Sir Isac Newton was the scientist who discovered why the planets stay in orbit.
What keeps the planets in the solar system in orbit around the sun?
The Sun's strong gravity keeps all the planets in orbit around it.
Who found that the force that keeps the planets in orbit around the sun and the moon in orbit around the earth and also acts upon bodies falling to earth is the same?
Sir Isaac Newton
What keeps the planets and moons in their orbit?
gravity
