A planet is kept in its orbit because the Sun's gravitational attraction on it produces acceleration towards the Sun, which exactly balances the force, by Newton's laws of motion.
An object that is travelling along in a curved path is accelerating to the side, according to Newton's theory, and in a stable orbit this can go on for ever without the energy ever diminishing.
What else can I help you with?
What factors keep the planets in orbit?
Gravity and inertia
Why do planets are always in orbit?
to keep gravity going
What are the 2 factors that keep the planets in orbit?
The two factors that keep planets in orbit are gravity and the forward motion they gained during their formation. Gravity pulls the planet towards the sun, but the forward motion prevents the planet from falling into the sun, leading to a stable orbit.
What does the sun do vfor the solar system?
the sun uses its gravitational pull to keep the planets in orbit.
How are the planets held in orbit?
Planets are held in orbit around the sun by gravity, which is the force of attraction between objects. The sun's gravitational force keeps planets moving in a curved path around it. The speed of the planet's movement and the gravitational pull of the sun balance each other to keep the planet in a stable orbit.
What two things keep the planets in their orbit?
gravity&inertia
What two things keep the planets in orbit?
The gravitational force from the Sun keeps planets in orbit around it. Additionally, the forward motion of the planets balances the pull of gravity, preventing them from falling into the Sun.
What two forces work together to keep the planets in orbit around the sun?
The two forces that work together to keep the planets in orbit around the sun are gravity and inertia.
Do the stars orbit the planets or do planets orbit stars?
Moons orbit planets. Planets orbit stars. Some stars orbit other stars, or orbit their mutual center of gravity. Stars orbit the center of the galaxy. Galaxies may orbit the center of the "galactic group".
How does the grivity effect the planets and moons?
Gravity helps to keep the planets in orbit. It also helps to keep the moon's close to the planets.
What factors keep the planets in orbit?
Gravity and inertia
Why do planets are always in orbit?
to keep gravity going
What 2 things keep your planets in an elliptical orbit?
Gravity and velocity (or inertia), and they aren't things. They're forces.
Does the suns gravity keep the planets in orbit around it?
Yeah
What does the sun's gravitational pull keep in orbit?
Planets, asteroids, meteors, comets, moons (which are also in orbit around their respective planets), dust particles, interplanetary gas.
What forces does the sun use to keep the planets in orbit?
solar power
Why do planets need their stars?
Planets need their stars for heat and light, which are essential for supporting life and maintaining stable surface temperatures. Additionally, the gravitational pull of the star helps to keep planets in orbit around it.
