The earth is very close to being a sphere, so its circumference is basically the same all around.
But because of a bit of a bulge around its middle, the equator is the longest of any circumference you could measure of the earth. Because of the bulge, the earth is really an oblate spheroid.
Just like every other body in a closed orbit, earth's orbital velocity is greatest at the time when
it's closest to the central body, which in our case is the sun. That point in earth's orbit is known
as "perihelion", and the earth reaches that point sometime in the first couple days of January.
January. =============================== The orbital speed of the earth in its path around the sun is greatest
when (and where) the orbit is closest to the sun. This point in the orbit
is known as "aphelion", and occurs in January.
The speed of the Earth's rotation - its spin - is constant. It doesn't speed up, and it is slowing down VERY slowly as it interacts with the Moon.
The speed of the Earth in its orbit around the Sun is greatest when it is closest to the Sun, which is around January 4. The Earth's orbit is an ellipse rather than a circle, but it is only about 3% elliptical.
At the equator, where the surface of the Earth is farthest from the axis. At higher latitudes, it isn't as far to go around the Earth following a parallel of latitude, but at the equator, it is about 25,000 miles around. Since the Earth rotates once in 24 hours, that means that any point on the equator is going at over 1,000 miles per hour!
In every closed orbit, the speed is greatest when the two bodies are closest together.
In our time, the earth is closest to the sun (at 'perihelion') at a moment during the
first few days of January. In 2010, it occurred during the first hour GMT on January 3.
If you stand exactly on the north pole or the south pole, then each 24 hours,
you don't move, you only twirl once around the center-line of your body.
But at the equator, you move all the way around the entire circumference of the
earth in 24 hours ... corresponding to a speed of about 1,038 miles per hour.
The point is called perihelion, or periapsis, and occurs in January.

Perihelion (from Helios = Sun), or the more general term periapsis. (It does become awkward to use scores of different words for the same concept, depending on whether the central body is the Sun, the Earth, the Moon, a black hole, the Milky Way, etc.)

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
earth orbital speed is 30 kilometers per second!!
Mercury, because it has the largest eccentricity - 0.2
Because Venus has less distance to travel than the Earth and is travelling faster. With an orbital speed of 35.02 km/s and an orbital period of 224.70069 days gives an orbital distance of 679,883,169.35km The Earth has an orbital speed of 29.78 km/s (Slower than Venus) and an orbital period of 365.256 days gives an orbital distance of 939,800,765.95km
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 Moon's orbital speed is greatest when it is at its closest approach to the Earth.
The earth's orbital speed has no influence or effect on its rotation.
Orbital speed of a satellite: v - orbital speed G - gravitational consatnt R - radius of earth h - height of orbit
Pluto orbits the Sun at an average speed of 4.66 km/sec.

Nope. Mercury has an orbital velocity of 47.9km/s, whereas Earth has an orbital velocity of 29.8km/s.
About 30 km/sec
The orbital speed of the Earth is 66,622 mph - 107,218 km/h

The speed is variable; faster while closer to the Earth, and slower further away. But the actual speed varies by the orbital distance.
