The mean orbital velocity of Earth is about 29.783 kilometers per second. That's the speed the planet is moving through space in its orbit about the sun. Earth's speed varies a bit because its orbit is slightly eccentric, but that's why we say meanorbital velocity.
One can calculate this value by knowing two facts:
1. The earth is approximately 150 million km from the sun (mean distance) and travels approximately in a circular orbit
2. It takes one year for the earth to complete one orbit around the sun
Using (1), we can calculate the circumference of the earth's orbit (C) using 2piR, where R is the mean radius. This gives us
C ~ 300pi million km
for the total distance traveled in one year. One can calculate the number of seconds in a year by
T = 365 days/year *24 hours/day*60 minutes/hour*60 seconds/minute
This is very close to 10pi million seconds (within 0.3%). The mean speed is then given by:
V = C/T ~ 30 km/sec
As can be seen, this simple calculation is within 1% of the accepted value.
30 kilometers/second.

The velocity a rocket must reach to establish an orbit around earth is called?
The velocity a rocket must reach to establish an orbit around the Earth is called orbital velocity. It is the speed required for an object to overcome gravitational pull and maintain a stable orbit around the planet. The orbital velocity depends on the altitude of the orbit and follows Kepler's laws of planetary motion.
The velocity a rocket must reach to establish an orbit in space is?
The velocity a rocket must reach to establish an orbit in space is called orbital velocity. It depends on the altitude of the desired orbit and the mass of the body being orbited. In general, orbital velocity is around 28,000 km/h for low Earth orbit.
Assume that the moon travel at constant speed in a circular orbit around the earth is the moon's velocity is constant?
Yes, since the moon is in a circular orbit around the Earth, its velocity is constant but its direction is changing continuously as it moves around the Earth. This constant velocity is necessary to maintain the circular motion without drifting away or falling into the Earth.
What is an elongated enclosed circle around the earth orbit?
An elliptical orbit is an elongated enclosed circle around the Earth. It is a path that gives the orbit its shape due to the gravitational pull between the Earth and the object. The orbit's shape varies depending on the object's velocity and distance from the Earth.
Why is Earths orbital velocity slowest on July 5?
Earth's orbital velocity is slowest on July 5 because that is when Earth is at aphelion, its farthest point from the Sun in its elliptical orbit. At this point, the gravitational pull from the Sun is weaker, causing Earth to move more slowly in its orbit.
What is the relationship between the moon's velocity and its orbit around the Earth?
The moon's velocity affects its orbit around the Earth. The moon's velocity must be balanced with the gravitational pull of the Earth to maintain its orbit. If the velocity is too slow, the moon may fall towards the Earth; if it is too fast, the moon may move away from the Earth.
Is the escape velocity from the center of the earth different from the escape velocity from Earth's orbit?
Yes, very much so.
The velocity required to keed a satellite in orbit around the Earth is called?

What is the significance of the linear velocity of Earth in relation to its orbit around the Sun?
The linear velocity of Earth is important because it determines the speed at which Earth travels in its orbit around the Sun. This velocity helps maintain the balance between gravitational pull and centrifugal force, keeping Earth in a stable orbit and ensuring that it completes its journey around the Sun in a year.
The average velocity of the earth in its orbit is about miles per hour?
66,000
How long would it take a satellite launched to a distance of 6700 from the center of the earth to orbit the earth?
For stable orbit @ 6 700 000 metres Velocity = sq. root ( G * mass earth / orbit radius ) = 7713.576 metres / sec Time for (sidereal) orbit = (2 * pi * radius) / velocity = 5457.56 seconds.
How is tangental velocity related to the moon falling around the earth?
Tangential velocity is the velocity at which an object moves along a curved path. In the case of the moon orbiting the Earth, the tangential velocity of the moon allows it to stay in its orbit and not fall into the Earth due to the balance between the gravitational force pulling it towards Earth and the centripetal force keeping it in orbit.
Can you consider earth as having a uniform velocity?
No. Earth's rotational velocity is slowing. Do you mean the velocity of Earth's revolution around the sun? The earth speeds up in its orbit until it reaches perihelion, and then slows until it reaches aphelion.
Velocity is the speed and direction a rocket must have in order to orbit he earth?
save
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.
