How was gravity and motion of the planets viewed historically before newton?

Prior to Newton, it was noticed that objects fall, and this was described as a tendency, rather than being mathematically analysed. It was explained that it is in the nature of heavy things to fall to the ground. Various theories existed about the motion of planets. It was generally believed, and is still believed by some, that planets move the way they do in order to give coded messages to astrologers so that you can find out if it is a good idea to try new things today, or whether your latest boyfriend will be faithful. The whole universe is actually about us, or so it was thought. At one time it was thought that planets and stars were embedded in invisible crystalline spheres, which caused them to move in the patterns that we observe.

What is the main factor that causes each planet to have a continual motion around the sun?
all planets when moving Gravity and inertia.
Do planets revolve around the sun along a set track?
Planets revolve on their axis. Separate to this motion, they also orbit the Sun. The force of gravity and the momentum of the objects keep them going.
Why sun cannot revolve to planets?
The sun has the most gravity within the solar system, which pulls all the other planets towards itself. See, the gravity in outerspace is different; it pulls all the balls (planets) together because there is gravity on the sun (every part of the sun) and the spheres create a spinning motion. Since there is no planet exceeding the size and weight of the sun, the sun cannot revolve any planets.
What law regarding inertia the planets would travel in a straight line into space Gravity is the outside force that keeps the planets in orbit about the Sun?
Galileo was the first to say that an object will continue in a straight line at constant speed unless acted on by a force. Newton's law of gravity and laws of motion were used to give a mathematical proof of the laws of planetary motion discovered by Kepler from measurements of the planets' positions done by Tycho Brahe at the end of the 16th century.
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 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 is the relation between Relativity Gravity and the Planets?
Relativity is a theory of gravity, and gravity governs the motion of planets. This is your answer in a nutshell. If you want a detailed answer, then I suggest you start studying general theory.
How do the planets orbit around the planet?
Planets orbit the sun in a counter clockwise motion, due to the balance between the Sun's gravity and the gravity of each individual planet.
How does gravity affect the motion of objects on planets orbiting the earth?
You know that no planets actually orbit the earth right? ...?
What keeps all the planets in their place?
the gravity of the sun pulls them in a circular motion.
What keeps the solar system in balance?
Gravity and motion. Gravity pulls the planets in and keeps them from flying away, while the velocity of the planets keeps them from being sucked in completely.
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 does gravity have to do with the motion of the planets?
The gravitational force between planets supplies the centripetal force that causes them to orbit each other.
How does the force of gravity affect the direction of motion of the planets?
earths rotation around the sun
Whose laws of motion keeps planets in their orbit?
Gravity keeps planets in their orbits.Newton's laws of motion and universal gravitation explain how orbits work, but have no influence whatsoeveron causing it to work that way.
What keeps planets from crashing into the sun?
Gravity draws the planets toward the sun so that they are essentially in freefall, but their sideways motion relative to the pull of gravity causes them to miss the sun by the time they would have fallen into it.
What creates earths motion?
the suns gravity pull creates the earths movement as well as the other planets
