∙ 14y agoAny object rotating around a fixed central point will always have a greater rotation speed the closer it is to center. Therefore Mercury, with an orbital speed of 47.9 km/s is the fastest. Here are all the planets in order
Planetary Mean Orbital Speeds in Km/s
Mercury - 47.9
Venus - 35.0
Earth - 29.8
Mars - 24.1
Jupiter - 13.1
Saturn - 9.6
Uranus - 6.8
Neptune - 5.4

∙ 10y agoThe one that is closest to the Sun, which is Mercury. The orbital velocity is proportional to the reciprocal of the square root of the distance from the Sun (derivable from Kepler's 3rd law).
So a planet 4 times further away would travel at half the speed. At 16 times further, it would travel at a quarter the speed.

What planet has the fastest orbital velocity?
Mercury
When is the earth orbital velocity the fastest?
perihelion
What is the orbital velocity of the planet mars?
55,000 mph
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."
The velocity a rocket must reach to establish an orbit around earth is called?
Orbital velocity, or Close orbital velocity.
What planet has the fastest orbital velocity?
Mercury
Which inner planet has the largest orbital velocity?
Mercury is the fastest orbiting planet in the inner Solar System, with an average orbital velocity of 47.87 km/s.
Which planet has the lowest orbital velocity?
Pluto is the planet that has the lowest orbital velocity relative to that of the earth. The orbital velocity of Pluto is 0.159.
When is earth's orbital velocity the fastest?
perihelion
When is the earth orbital velocity the fastest?
perihelion
What describes the speed of a planet traveling in an elliptical orbit around the Sun?
As the planet approaches perihelion (point of nearest approach to the Sun), its orbital velocity gets faster, and it is fastest at perihelion. Similarly, at aphelion (point of furthest approach to the Sun), the orbital velocity is slowest.
Which term refers to the speed at which a planet travel in its orbit?
Orbital velocity refers to the speed at which a planet travels in its orbit.
What is the orbital velocity of the planet mars?
55,000 mph
Which planet of your solar system has the fastest orbiting speed?
Mercury has the fastest orbital velocity, at about 49 thousand kilometers per second.Mercury: 48.651Venus: 34.874Earth: 29.663Mars: 24.025Jupiter: 13.012Saturn: 9.604Uranus: 6.749Neptune: 5.410These number are based on major-axis, and on an assumed circular orbit, so they will not agree with the official stated mean orbital velocity.
What is the speed of Jupiter planet?
Jupiter has an orbital velocity of 13.1km/s.
Which planet has Similar tilt axis of ration angle than earth?
which planet has the slowest orbital velocity
Which planet revolves faster around the sun?
Mercury has fastest orbital speed.
