What is the name for a planet's speed in its orbit?

It is the orbital velocity (speed and direction) or orbital speed (rate of motion). It is usually stated as "average orbital speed" but is actually "mean orbital speed."


Which planets orbital speed is thirty kilometers per second?

The planet with an orbital speed of around 30 kilometers per second is Earth. Its average orbital speed around the Sun is approximately 29.78 kilometers per second.


What is Orbital Speed?

Orbital speed is the velocity required for an object to stay in a stable orbit around another body, like a planet or a star. It is determined by balancing the gravitational force pulling the object towards the center with the object's inertia carrying it forward. The speed needed for orbit depends on the mass of the central body and the object's distance from it.


Which planet has the slower orbital speed Saturn or Jupiter?

Saturn is slower because it is farther from the sun. The farther away a planet is from the sun, the slower its orbital speed.


Which outer planet moves around the sun the fastest?

The outer planets are usually defined as Jupiter, Saturn, Uranus and Neptune. The innermost of those, Jupiter, moves around the sun the fastest. The speed of planet is a function the size of its orbit only -- mass doesn't matter, as figured out by Kepler about 500 years ago. Thus Mercury, the innermost of all planets, has the greatest orbital speed (87.96 Earth days for an orbit), and Neptune the slowest (164.81 Earth years). If you want to include Pluto, then it has the greatest orbital period (247.7 earth years)

What is difference between orbital and spinning speed of a planet?

The orbital speed of a planet is the time it takes to cycle around the sun. The spinning speed of a planet is the time it takes for the planet to rotate on it's axis.


What is the speed of Jupiter planet?

Jupiter has an orbital velocity of 13.1km/s.


Why do planets differ in their orbital speed?

Because according to Kepler's laws the orbital speed of a planet is proportional to the square root of the reciprocal of the distance: v = d-½.


What is the average orbital speed of the planet neptune?

5.43 km per second.

If the planet has less gravitation pull does that effect the speed it orbits around the Sun?

No. A planet's gravitational pull is determined by the planet's mass. A planet's orbital speed is determined by the the mass of the Sun and the planet's distance from the Sun.
