The prime force that keeps a planet's orbit around the sun is called "gravity".
There seems to be an attraction between molecules and bodies in free space.
If these bodies possessed no existing momentum in some other direction ... in other words, if these bodies were more or less 'still' in space (which they are not - all things are in motion) ... but if they were still, they would immediately commence moving towards one another. As gravity is a Force, and forces possess an acceleration component, their attraction towards one another would pick up speed indefinitely - moving ever faster until they collided with one another with quite some impact.
The size or "mass", specifically, of a body also determines the force of gravity which it exerts on other objects.
But as bodies are naturally all moving in a direction within space, there exists some interplay between their mass, their existing direction of movement and the force of attraction that exists between these bodies in question.
It seems, however, that design is such that bodies are moving in a set path. They seem to be in position such that their natural momentum in space is just sufficiently 'reigned in' enough by the gravity or the attraction that exists between these bodies that they are maintained in some perceptibly 'fixed' orbit around the sun. Of course, in addition to the sun, there are other moving bodies and forces out there which are also involved and which also exert some influence upon the orbit of any one planet and cause an interplay which affects the whole system generally: it is not merely a fact of the dual relationship between just the planet and sun. The many other objects in existence all carry their effect as well. There exists quite a complexity of involvement between all bodies.
Neither is it merely 2-dimensional, as we are often wont to imagine. Many bodies revolve at various angles to the planes at which other bodies and planets move in space! Some move in an orbit that almost meets at a perpendicular to most of the system.

How does the sun stay in orbit around the sun?
The Sun's gravity keeps the Earth (and all the planets) in orbit around it. Yes, but obviously there's more to it or the planet would go into the Sun. It is the Earth's orbital velocity ( technically known as its tangential velocity) which, together with the force of gravity, keeps the Earth in orbit.
What force keeps us from floating of into the stay and to keep the planets in orbit around the sun?
Answer:because the sun is like a big ball of mass which means that the planets pull the mass from the sun which keeps the planets in their rotation but if there was not mass then all the planets would go on a straight line.
What keeps the earth and all the planets and suns floating in thin air?
Gravity is the force that keeps the Earth and other celestial bodies floating in space. Gravity is the attraction between objects with mass, pulling them towards each other. It keeps planets in orbit around the Sun and moons in orbit around their planets, creating a delicate balance that keeps everything in place.
What keeps all of the planets in its orbit?
Gravitational attraction to the sun
How are all the planets kept in orbit by gravity?
The sun's gravity exerts a constant force on each planet in the direction straight toward the sun, but the law of inertia tries to keep the planet moving in a straight line. The resultant force from the vector addition of those two forces keeps the planet in its orbit.
What are forces that keep the moon in orbit around the earth?
Gravity keeps planets in orbit as it spins it creates gravity and gravitational pull keeps the a lined
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.
What hold the planet in orbit around the sun?
The planets orbit the Sun because of the force of gravity that keeps them there. Without gravity they would all move in straight lines.
What type of force provided by the suns gravity keeps the planets in orbit?
the gravititonal pull does; it is what keeps all the planet in the suns orbit xx
How does the sun stay in orbit around the sun?

It is the Earth's orbital velocity ( technically known as its tangential velocity) which, together with the force of gravity, keeps the Earth in orbit.
What keeps the planets in our solar system in orbit around the Sun?
The Sun's strong gravity keeps all the planets in orbit around it.
Why do planets continue to orbit around the sun?
The force of gravity keeps the planets in their orbits, and without it they would all go off in straight lines into interstellar space.
How do gravity and inertia keep the planet in orbit around the sun?
inertia keeps the planets moving and spinning , and gravity is a force that attracts all objects toward each other.
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.
How does gravity affect the relationship between the sun and the planets?
Yes. It keeps the planets in orbit around the Sun.
What force keeps the moons of Jupiter in orbit around the planet?
The moons stay in orbit around Jupiter by the force of gravity.
What keeps the planetsin orbit around the sun?
gravity keeps all the planets in rotation around the sunThe shape of orbits, and their existence, is the result of the mutual force ofgravitational attraction between every two bits of matter in the universe,and the specific way it works. So short answer = gravity.
