Why is earth not effected?
Earth is not affected by the gravitational pull of other objects in space because it is in a stable orbit around the sun. The gravitational force between the Earth and the sun is much stronger than the gravitational pull from other objects in space. Additionally, Earth's distance from these objects and its velocity allow it to maintain its orbit without being significantly affected.
Do bigger objects orbit closer to the than smaller objects?
No. An object of just about any size can orbit at any distance.
How do objects in space move around other objects in space?
Objects in space move around other objects due to gravitational forces. These forces cause objects to orbit around a more massive body, like planets around a star, based on their mass and distance. The path an object follows is known as an orbit and is determined by a balance between the object's velocity and the gravitational pull of the larger body.
Is the perimeter of a planet's orbit determined by how big or small it is or how hot the sun makes the planets?
NO, the orbit of any planet or moon is determined by the size of the two objects involved (example: the Earth and the Sun) and the distance between those two objects: the closer the objects are to each other and the bigger one of the objects is, the stronger the gravitational pull ( large objects have stronger forces on other smaller objects). The orbit of a planet has nothing to do with the Sun's heat.
Which identifies the objects in your solar system that are affected by the force of gravity?
They are all in orbit.
Why doesn't the moon crash into Earth?
The moon doesn't crash into Earth because of its orbit and the balance of gravitational forces between the two objects. The moon's speed and distance from Earth keep it in a stable orbit, preventing a collision.
What is the distance from earth where gravity becomes zero?
There is no such distance. Gravity has no limit. There are forces of gravity between the lint in your pocket and the smallest grain of sand on the farthest beach on the other side of the farthest planet, in orbit around the farthest star, in the farthest galaxy from Earth. Of course, the farther apart two objects are, the less the gravitational forces between them are. But the forces are still there.
What are the efffects of gravity?
Gravity keeps your feet on the ground. Gravity keeps all orbiting objects in orbit around the object they are orbiting. The force of gravity decreases as a square of the distance between two objects. Gravity is the weakest of the fundamental forces. Gravity is an attractive force between any two objects that have mass.
Are all planets affected by the sun?
All planets and other objects in the solar system orbit the Sun because of its gravity.
What Two factors that affect the gravitational attraction between objects are?
Two factors that affect the gravitational attraction between objects are the mass of the objects and the distance between them. The greater the mass of the objects, the stronger the gravitational attraction, while increasing the distance between the objects weakens the gravitational force.
Why do the planets and other objects in the solar system stay in their orbit?
Each planet remains in orbit because of the pair of equal gravitational forces that attract it and the sun toward each other.
Are planets objects?
Yes, planets are astronomical objects that orbit a star, have sufficient mass for their self-gravity to overcome rigid body forces so that they assume a nearly round shape, and have cleared their orbit of other debris.
