Orbital speed of a satellite:
v - orbital speed
G - gravitational consatnt
R - radius of earth
h - height of orbit
If something is in orbit it's orbital speed is independent of its mass. Be it a gram or a tonne, it's speed depends only on its orbit; if it had a different speed it would be in a different orbit ( or none at all).
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."
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.
Orbital speed is the velocity (speed) of an object as it travels an orbital path around a reference point.
Orbital velocity refers to the speed at which a planet travels in its orbit.
Orbital speed = (circumference of the orbit) / (period of revolution)
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.
There are about 63 known moons of Jupiter but the Galilean moons are the 4 moons visible and Ganymede ,the largest found by Galileo Galilee in January 7 1610.The orbital speed of the Jovian moons vary where the Jupiter's magnetic field is very strong.Only a mean speed can be used for comparison.The four moons and their orbital speed compared to the orbital speed of Earth's moon are:Jovian Moons Orbital speed/ Orbital speed Ratio(km/s) (Earth's moon)1. Io orbital speed 2.75 km/sEarth's moon orbital speed 1.03 km/s Ratio 1: 2.672.Europa orbital speed 2.187 km/sEarth's moon orbital speed 1.03 km/s Ratio !: 2.123. Callisto orbital speed 1.732 km/sEarth's moon orbital speed 1.03 km/s Ratio 1: 1.684.Ganymede orbital speed 1.305 km/sEarth moon's orbital speed. 1.03 km/s Ratio 1: 1.27
Titan, Saturn's largest moon, has an orbital speed of about 5.57 km/s. This means it travels around Saturn at an average speed of 20,052 km/h.
The earth's orbital speed has no influence or effect on its rotation.
The mass of the Sun and the distance between the planet and Sun. As the Sun's mass is (more or less) constant, all we need to know is the distance. Technically this is called the "semi major axis" of the elliptical orbit. (If you wanted to be really, really accurate the mass of the planet does have a very very small effect.)
According to http://solarsystem.nasa.gov/planets/, Venus has an orbital velocity of 78,341 mph, and Neptune's is 12,253 mph...
