Gravity
Gravity is the force that brings all things together.
The gravity, between the Sun and the planets.
If you was a general answer, all of them. However if you want a technical answer, none of them, being that all objects, including the sun, orbit the center of mass of the solar system.
Gravity from the sun keeps the planets in the solar system.
Gravitational force.
Everything has a center of gravity, and a gravitational pull. For example, what keeps Earth from floating off into space? Answer: The Sun. The sun is what we're orbiting because it has a massive gravitational pull at it's center pulling our smaller planets towards it.
The gravity from the sun attracts the planets, vs the speed of the planets keeping them from falling into the sun.
I believe earth is traveling about 2,000 miles an hour.
It's all about SPEED, MASS, GRAVITY and maintaining an equilibrium.
The planets want to go straight out into the void, but the pull of the sun keeps it curving around the sun.
The mass of the sun is much greater than it's planets, so everything with mass will be drawn to the gravity pull of our Sun.
So, it's the particular speed of the planets that maintain the orbit, and keep them from flying out into space, or from sinking into the Sun.
This is relatively stable, although all planets also effect each other, changing slightly the path of their orbits.

The strong gravitational pull of the gas giants, such as Jupiter and Saturn, keeps the gases from escaping into space. The immense mass of these planets creates a powerful gravitational force that holds the gases in their atmosphere. Additionally, the presence of a magnetic field around these planets also helps in trapping the gases and preventing them from escaping.
The planet's strong force of gravity holds the atmosphere down and stops it escaping. Atmospheric gases have masses, and the Earth's atmosphere has a mass of about 1.2 kg per cubic metre.
The force is gravity. Gravity is the force of attraction between two objects with mass, and the sun's gravitational pull keeps the members of the solar system bound to it, causing them to 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.
The force that keeps planets in orbit is gravity. Gravity is the attractive force that exists between two masses, such as a planet and a star, that causes them to be drawn towards each other. In the case of planets orbiting a star, gravity keeps the planets in their elliptical paths around the star.
The force of the Sun's gravity keeps them in their orbits.
The force that keeps all of our planets in rotation is gravity.

Gravity is the force that connects the solar system to the sun.

The force of gravity.
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.
The gravity of there star keeps them on path and a planets moon is sun around by its planets gravitational force
The gravitational force between the sun and the planets keeps them in orbit. This force acts as a centripetal force that continually pulls the planets towards the sun, keeping them in a stable orbit. The balance between the planet's velocity and the gravitational force determines the shape and size of their orbits.
Planets in our solar system are kept in orbit by the gravitational pull of the sun. The balance between the centrifugal force of the planet's movement and the gravitational force of the sun keeps them in a stable orbit.
The force of gravity between the planets and the sun keeps them in orbit and prevents them from flying out of the solar system. The sun's gravitational pull keeps the planets in stable orbits around it.
