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.
It was Isaac Newton who figured out that the force of gravity keeps planets in orbit around the sun.
Newton concluded that the force of gravity between the planets and the Sun keeps them in orbit. This force is proportional to the product of their masses and inversely proportional to the square of the distance between them, as described by his law of universal gravitation.
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.
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.
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.

That force is gravity.
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.
orbit
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.
If no force, the planets would move in a straight line, not in a orbit around the sun.

Sir Isac Newton was the scientist who discovered why the planets stay in orbit.
Planets orbit around the Sun because of the Sun's gravitational force, it makes the planets move by its gravitational force.
Newton's theories of gravity and the laws of motion, with the differential calculus he also invented (Leibnitz did the same in Germany), explained why the planets and other objects obey Kepler's laws of planetary motion, which were deduced from observations. It happens because of the Sun's gravity, an inverse-square force (which means that the force reduces with the square of the distance). Newton showed that a central force of this type produces an orbit exactly as Kepler had described many years before. Different planets at different distances, with a range of different initial conditions, take up a family of orbits that all follow the same theory.
