Its speed will vary greatly as its orbit is highly eccentric. It will be slower when further out from the sun on its 11,000 year orbit. Its average speed is around 1.04 km/s.
Orbital velocity refers to the speed at which a planet travels in its orbit.
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.
Sedna
According to http://solarsystem.nasa.gov/planets/, Venus has an orbital velocity of 78,341 mph, and Neptune's is 12,253 mph...
Sedna is not a planet, according to the International Astronomical Union (IAU). Because Sedna is so distant and so small, it has not yet been classified, but is probably a Trans-Neptunian Object. It may or may not turn out to meet the standards of a "dwarf planet", depending on whether its mass is high enough to force it into a roughly spherical shape. Sedna's orbit is highly elliptical and has not been completely analyzed, but its perihelion appears to be 76 AU with an aphelion of 975 AU. This would give it an orbital period of perhaps 12 thousand years.
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."
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 of a satellite: v - orbital speed G - gravitational consatnt R - radius of earth h - height of orbit
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
The dwarf planet Sedna is believed to have an orbital period of about 11,400 years. It orbits at a distance between 76 and 937 astronomical units.
Not "a" Sedna; just "Sedna". Sedna is the Inuit goddess of the sea. Also, a dwarf planet named after this goddess.
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.
