neptune is the furthest actual planet from the sun, approx 3 miles per second. although, pluto (now a dwarf planet) is approx 2.5 miles per second.
Pluto is the planet that has the lowest orbital velocity relative to that of the earth. The orbital velocity of Pluto is 0.159.
Orbital velocity refers to the speed at which a planet travels in its orbit.
Mercury is the fastest orbiting planet in the inner Solar System, with an average orbital velocity of 47.87 km/s.
Mercury
55,000 mph
The planet Mercury has the shortest orbit time, because it is the closest to the sun.
Jupiter has an orbital velocity of 13.1km/s.
Mercury.
which planet has the slowest orbital velocity
The orbital period of Saturn is 29.4571 years. Its orbital velocity is 9.69 kilometers per second and the orbital path is about 9 billion kilometers.
Orbital velocity is the average velocity (or speed) of a planet as it orbits around the sun. It is usually expressed as km/s or mph.
because it is one of the lightest planet and it is not that close to the sun
