Newton's model, which is still current for most purposes (with slight modifications by Einstein) has planets held in their orbits by gravitational attraction between Sun and planet.

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 three things keep the planets in their orbit?
A planet is kept in its orbit because the Sun's gravitational attraction on it produces acceleration towards the Sun, which exactly balances the force, by Newton's laws of motion. An object that is travelling along in a curved path is accelerating to the side, according to Newton's theory, and in a stable orbit this can go on for ever without the energy ever diminishing.
What did newton made about the Moon's orbit around the earth?
Newton proposed a formula to describe how gravity works. Then he showed thatif his formula is correct, then gravity is the force that makes bodies orbit other bodies,and that the moon and planets must have orbits exactly like the ones that they reallydo have.
Why do our planets remain in orbit father of calculus?
The Sun's gravitational force controls all the orbits of planets and other objects that orbit the Sun (dwarf planets, asteroids, comets, meteors).An object without a force acting on it travels in a straight line, But the Sun's gravity causes each object to accelerate towards the Sun, as described by Newton's second law: force = mass x acceleration.The acceleration causes any fast-moving object to curve towards the Sun, as Newton discovered using calculus. This is a permanent process with the object in a stable orbit unless disturbed by a collision of some sort.
A force that keeps planets in orbit?
Centripetal Force.That force is, of course, supplied by gravitional force.
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 force did Newton say kept the moon and planets in orbit?
That force is gravity.
Did Kepler say that it was the pull of the suns gravity that kept the planets in orbit?
No. Kepler proposed that some force kept the planets in orbit, but did not know or say what that force was. It was Isaac Newton who figured out that this force is gravity.
What force did Sir Isaac Newton say helped keep the planets moving around the sun?
orbit
Which scientist explained why planets orbit the sun and moons orbit the planets?
ANSWER Sir Isak Newton was the first person to realise that the force of gravity was universal. It is Kepler motion that describes the elliptically orbits of the planets.
How could newton's first law of motion explain that a force is acting between the sun and its planets?
If no force, the planets would move in a straight line, not in a orbit around the sun.
Who realized the attractive force between any two objects in the universe that causes the orbit of the planets to curve?
Newton
Who explained why planets stay in their orbit?
Sir Isac Newton was the scientist who discovered why the planets stay in orbit.
Why do all the planets orbit?
Planets orbit around the Sun because of the Sun's gravitational force, it makes the planets move by its gravitational force.
What three things keep the planets in their orbit?
A planet is kept in its orbit because the Sun's gravitational attraction on it produces acceleration towards the Sun, which exactly balances the force, by Newton's laws of motion. An object that is travelling along in a curved path is accelerating to the side, according to Newton's theory, and in a stable orbit this can go on for ever without the energy ever diminishing.
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
How did newton use observations of nature to explain the movements of planets?
He once saw an apple falling from a tree, and he wondered whether the force that pulled that apple to earth might also control the movements of planets. In the next 2o years, Newton perfected his theory. Using mathematics, he showed that a single force keeps the planets in their orbit around the sun. He called this force gravity (:
