What force works with gravity to keep the planets from being pulled into the sun?

That's "centrifugal force". It's not a "real" force like gravity, but is a convenient way of describing the effect of the inertia of the planets. (The planets would move in straight lines if they were not in a gravity field.)

What keeps astronauts from being pulled by the earths gravitational force?
Nothing keeps them from being pulled. Earth's gravity certainly pulls on them.
Are all planets held by a force called gravity?
Not all of the planets are held by gravity.
What keeps the planets from being pulled to the sun's suface by gravity?
The energy of their rotation round their orbits acts against the central force of gravity, in the same way as a ball on a string can be whirled round even though the tension in the string is pulling the ball towards the centre all the time.
Why moon is not pulled away from the earths sun?
The Earth, Moon and other planets stay in their orbits under the force of gravity, following Kepler's laws of planetary motion.
What force keeps planets around the sun?
Gravity.
Which force affects the motion of planets?
The motion of the planets are governed by a number of factors: Gravity - The planets are being pulled towards the Sun in free fall. The velocity of the planets - This balances against the force of gravity opposing it and producing on balance the orbit. The mass of the planets. The effect of gravitational attraction between the planet and any satellites it has. The effect of gravitational attraction between the planets and other planets/dwarf planets etc.
What controls the motions of the planets?
Gravity is what sets the planets in motion. The force that keeps them in motion is known as inertia in the law of physics.
What keeps astronauts from being pulled by the earths gravitational force?
Nothing keeps them from being pulled. Earth's gravity certainly pulls on them.
What force would pull two spheres together?
They are being pulled by the force of gravity
Gravity is the reason that the planets stay in orbit around the sun?
It is half the reason, at least. Gravity is the force pulling the planets towards the sun, but they also have a velocity working perpendicular to it. With the velocity alone, the planets would fly off into space. With gravity alone, the planets would be pulled into the sun.
What kind of force there is in orbiting planets?
The planet moves forward in its orbit while being pulled sideways by gravity acting between it and the Sun. Isaac Newton showed that each planets obeys the laws of motion and must follow an elliptical orbit that obeys Kepler's laws when the force of gravity is inversely proportional to the square of distance.
What is the difference centrifiugal force and centripetal force?
centripetal is the force pulling towards the center of a circle. And centrifiugal is artificial gravity. It makes you "feel" like you are being pulled into one direction when you are being pulled to the other.
Is rain a force?
No. What brings rain down, gravity, is a force. Rain is simply water being pulled down by gravity in little drops from clouds in the sky.
Which force causes comets to return to the inner planets after being gone so long?
Gravity. Specifically, the gravity of the Sun.
Are all planets held by a force called gravity?
Not all of the planets are held by gravity.
What part does gravity play in the paths of the planets?
Gravity is the force which directs the path of the planets.
What are two factors that determine the size of the force of the gravity?
-- the massses of the two masses that are being pulled together by gravity -- the distance between them
