It is because the planets have a linear velocity and due to their inertia and no air resistance(vacuum), they retain their linear momentum. When the Sun's gravity pulls on the planets it does so at a 90 degree angle so all it can do is make it revolve around the Sun since perpendicular forces don't affect each other.
So the planets have a linear speed which is not affected by the sun's gravity and at the same time are pulled at by the sun's gravity.

∙ 14y agoThe inertia from the planets combined with the strong gravitational pull from the from the sun keep them from running into each other and also keeps the planets from hitting the sun.
While the gravitational pull from the sun attracts the planets, the planets inertia (resistance of a moving object to change direction) will keep the planets in orbit.

∙ 13y agoBecause of earths gravitational field. Although it is weaker, the sun is a lot further away. Also the wight of the air above you that you would hae to push through to get into space to orbit the sun is exraordinary

Because we are all also in orbit round the Sun. If we stayed where we were and the Earth magically vanished, we would still go round in the same orbit in 365 days because the orbital period depends only on distance. So we are in free-fall round the Sun and our inward acceleration is balanced by the Sun's gravity acting on us, so we feel no force from the Sun.

∙ 6y agoEarth is continuously pulled toward the sun by gravity. However, it is moving so fast relative to the sun that, in effect, it continuously misses by about 93 million miles. Since we are pretty much the same distance from the sun that Earth is, we easily follow the same path. It also helps that we are held to Earth by Earth's own gravity.

You jump off a truck and accelerate toward the surface of the Earth Does the Earth accelerate toward you?
Yes, because you attract the earth with the same gravitational force that the earth attracts you.
What energies do you get from the sun?
The energy that the sun gives off are heat and light. Living things on Earth need these forms of energy.
What does earth's energy budget mean?
It's the amount of energy given out by the sun, and the energy received by the earth. Within that is the energy reflected and the energy given off from the earth.
When a diver jumps off a diving board gravity pulls him or her to the water What is the reaction force to Earth's gravity?
Gravity always acts as a pair of forces, not as one single force. The strength of the forces depends on both masses, not just one of them. The forces of gravity attract the diver toward the earth and the earth toward the diver. The forces are equal in both directions. If the diver weighs 150 pounds on earth, then the earth weighs 150 pounds on the diver. The diver accelerates toward the center of the earth with an acceleration equal to (weight)/(diver's mass), and the earth accelerates toward the diver with an acceleration equal to (weight)/(earth's mass). Has that helped, or just confused the issue further ?
How does the sun's gravity affect the planets?
Yes. The sun is attracted by the gravity of the planets just as the planets are attracted by the sun. Since the sun is more massive it does not move as much, bu the gravity of the orbiting planets does cause it to "wobble."
Could you please give your description for moonlight?
moonlight is the sun's light reflecting off the moon and beaming toward earth.
What is different between sun and moon?
The sun is a giant nuclear fusion reactor and everything in the solar system orbits around it or is pulled into it by the sun's gravity and is destroyed. The sun gives off heat, light and radiation. The moon is a rock that orbits the earth.
You jump off a truck and accelerate toward the surface of the Earth Does the Earth accelerate toward you?
Yes, because you attract the earth with the same gravitational force that the earth attracts you.
During winter months does earth travel away from the sun?
If one end of the earth's axis is leaning away from the sun, then the other end must be leaning toward it. Whichever half of the earth happens to be leaning away has Winter, while the half that's leaning toward the sun at the same time has Summer at the same time.
Does it take the earth 400 days to orbit the sun?
First off, the Earth orbits the sun. Second off, no. The time it takes the Earth to orbit the sun is a year. A day is the time it takes the Earth to rotate on its axis.
What gives off its own light the sun the moon or the earth?
The Sun.
The sun the moon and the Earth are all linked by gravity The sun pulls more than twice as hard as the Earth so why doesn't the moon go flying off to be with the sun?
Because the sun doesn't actually pull harder than the earth does. The basics of orbital mechanics show us that if something is at the right distance and going at the right speed, it will stay at that same distance and speed until virtually forever. The earth also orbits the moon while the moon orbits it, and the resulting centre of mass is what actually orbits the sun. because three is nothing to stop either of these orbits, the moon and earth continue to orbit the other and the centre of mass continues to orbit the sun. Besides this, the moon is pulled away slightly when it is between the sun and earth, but is pulled back to the earth when the earth is between the moon and sun. This creates some imbalance in the distance the moon is from earth, and in total the average is a certain distance which results in the moon staying right where it is; next to earth.
Why does the moon and the sun can't fall?
The moon does fall toward the earth, but it is in pseudo-equilibrium with its momentum. Think of the moon as a baseball that's been batted so hard, it actually falls over the horizon -- over the curvature of the earth. It is in freefall around the earth. It circles around the Earth which circles around the sun, but if the Earth and Sun were to somehow suddenly not exist, the Moon would travel in a straight line instead of in a circle. The Earth actually does the same to the Sun -- the Earth falls over the Sun's horizon. Earth's gravity is strong, and no human astronaut has actually ever escaped it -- the reason astronauts experience weightlessness in orbit is not because the earth's gravity no longer affects them (if it did not, the spacecraft they are in would fly off into deep space instead of orbitting the earth), it is because they are in freefall; you would obtain the same effect if you were in an airplane plummeting straight down toward the earth.
Why is the moon illuminated?
Light from the sun is reflected off the moon back to the earth, which is why the moon looks illuminated. sun-----------------> moon earth <-------
Is it true that a satellite is always being pulled by gravity?
Yes it is true. There is no way to turn gravity off or shield anything from it, so everything is always being pulled toward everything else by gravity.
Does the sun turn off?
The answer is no its on every day but the earth rotates and wherever the the sun is shining that the place theres sun
Does the sun's light reflect off the moon to earth?
Yes it does.
