There are two factors that are balanced just right to keep the planets in their orbits; the tangential velocity, and the gravity. The planets have a tangential velocity, they are speeding along sideways relative to the sun. If there was no gravity, this velocity would take the planets away from the sun, but the sun has a huge gravitational force which counteracts this effect. The suns gravitational force is constantly attracting the planets in, against this tangential velocity. If the planets were to slow down, then they would eventually spiral into the sun, but in space there is no drag, so the planets maintain their speed and their orbits.
What else can I help you with?
Would Saturn still be a planet without its ring?
Yes, because it orbits the sun and keeps a constant orbit.
What is the force that keeps planet in orbit?
the suns gravity keeps the planets in orbit
What keeps a planet in orbit?
Gravity and its velocity
What keeps a moon in orbit around a planet?
gravity :)
Inertia makes a plant tend to travel in a straight line but what keeps it in orbit?
Gravity keeps a planet in orbit. Inertia tries to make the planet move in a straight line. The balance between the two makes the planet orbit a sun.
Inertia makes a planet tend to travel in a straight line but what keeps it in orbit?
Gravity is what keeps a planet in orbit around the sun. The gravitational pull between the planet and the sun causes the planet to continuously fall towards the sun, but its forward motion prevents it from getting any closer and keeps it in a stable orbit.
What keeps a satellite in orbit around a planet and why?
the forse of gravity keeps it floating in space like the moon orbits our planet
What force keeps a planet in its orbit around the sun?
gravity
What force keeps a planet or moon in its orbit?
GravityCentripetal Force.
What force keeps a planet in its orbit around the sea?
Gravity
How are all the planets kept in orbit by gravity?
The sun's gravity exerts a constant force on each planet in the direction straight toward the sun, but the law of inertia tries to keep the planet moving in a straight line. The resultant force from the vector addition of those two forces keeps the planet in its orbit.
What type of force provided by the suns gravity keeps the planets in orbit?
the gravititonal pull does; it is what keeps all the planet in the suns orbit xx
