The Sun's gravity keeps the planets in their orbits. Without gravity they would all move in their own straight lines, but the central force keeps them curving inwards towards the Sun continuously, while their sideways velocity stops them falling in completely.
What else can I help you with?
What holds all moons to every planet in their orbits?
Gravity. As the planet rotates it's mass holds it's moons within it's orbit. The larger the planet the stronger is its gravitational pull.
What force is responible for the orbits of the planets in the solar system?
Gravity from the Sun holds the planets in their orbits.
What makes a planet orbits the sun?
Gravity is the force that allows a planet to orbit the sun.
What is the name of the force which keeps the planet in their orbits?
the name of the force iis called gravity or its gravitational pull
What holds the moon in orbit?
The gravitational force between the moon and Earth keeps the moon in orbit. This force pulls the moon towards Earth, but the moon's velocity allows it to continue moving in a circular path around the Earth.
What force holds a planet's atmosphere in place?
Gravity holds the atmosphere around the planet. Gravity is the force that attracts a body toward the center of the planet. For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account.
What forces act to hold a planet in orbit around the sun?
The gravitational force between the planet and the sun is what holds the planet in orbit around the sun. This force keeps the planet moving in a curved path around the sun, in balance with the planet's inertia.
Why is a moon not a planet?
A planet orbits a star such as the sun. A moon orbits a planet.
Which type of force holds the plants in orbits around the sun?
The elliptical shape of each planetary orbit is the result of the adding together the forces of gravity, which tries to move each planet toward the sun, and inertia, which is trying to keep each planet moving in a straight line.
What keeps planets in elliptical orbits?
Planets are kept in elliptical orbits due to the gravitational force acting between the planet and the sun. This force causes the planet to move in a curved path, resulting in an elliptical orbit. The balance between the planet's inertia and the gravitational force determines the shape of the orbit.
Is a planet a moon?
No. A moon orbits around a planet. A planet orbits around the sun.
How is planet different from moon?
A planet orbits a star whereas a moon orbits a planet.
