How does the tangential velocity of a planet relate to it orbiting around the sun?

∙ 11y ago
The tangential velocity is equal to the circumference of the orbit divided by the time taken to go round once. For the Earth that is 2pi time 149.6 million kilometres divided by 365.25 days, which comes to 2.57 million km per day or 30 km/sec.

Which planet has the most suns orbiting around it?
Planets do not have suns orbiting around them. Suns have planets orbiting around them. The planet in our solar system with the highest number of discovered moons orbiting around it is Jupiter, with over 100.
What is the third planet orbiting around the sun?
Earth - The planet we live on.
How does the sun stay in orbit around the sun?
The Sun's gravity keeps the Earth (and all the planets) in orbit around it. Yes, but obviously there's more to it or the planet would go into the Sun. It is the Earth's orbital velocity ( technically known as its tangential velocity) which, together with the force of gravity, keeps the Earth in orbit.
What 2 forces combine to keep a planet in orbit?
There are two factors; the tangential velocity, and the gravitational force. 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 do you call a lump of rock orbiting around a planet?
It is considered a satellite.
What two types of motions keep a satallite in orbit around earth?
A tangential velocity vector relative to the orbit itself, and acceleration towards the center of the planet due to gravity.
Which planet has the most suns orbiting around it?
Planets do not have suns orbiting around them. Suns have planets orbiting around them. The planet in our solar system with the highest number of discovered moons orbiting around it is Jupiter, with over 100.
Which inner planet has the largest orbital velocity?
Mercury is the fastest orbiting planet in the inner Solar System, with an average orbital velocity of 47.87 km/s.
What is the third planet orbiting around the sun?
Earth - The planet we live on.
What two factors cause planets to move in elliptical orbits?
The elliptical orbit of planets is a result of the gravitation of the sun and the tangential velocity of the planet.

Is the velocity of any satellite 0 with reference to cos theta?
velocity of any satellite revolving around any planet is 0 with reference to cos theta. the velocity in circular motion is taken in tangential direction. when the velocity of any satellite is taken tangential , then it forms 90 degrees with the radius of the Earth. we know that cos90 = 0. therefore,velocity of satellites is 0 with reference to cos theta. but this contradicts the fact that " any body with 0 velocity would collide the Earth" stated by Issac Newton. scientists are still researching to get an appropriate answer to this question. - by d.s.rahul
What two factors act together to keep the planets in orbit around the sun?
definetly Gravity and Inertia
Is the velocity of all the satellites zero since cos90 equals 0?
in my opinion, the velocity of any body moving in a circular path is directed in tangential direction. when the velocity is took tangential,its angle formed with reference to the earths radius is 90 degrees. we know that cos90 = 0. therefore,the velocity of the satellites revolving around the earth must be 0 with reference to cos theta. velocity of any satellite revolving around any planet is 0 with reference to cos theta. but this contradicts the fact that " any body with 0 velocity would collide the Earth" stated by Issac Newton. scientists are still researching to get an appropriate answer to this question. - by d.s.rahul
Does Planet Earth have small planets around it?
No. There are no planets orbiting Earth.The Moon is not a planet.
What keeps a planet in its constant orbit?
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.
