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.
The point is called perihelion, or periapsis, and occurs in January.

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.

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.
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.)
The orbital speed of the earth ... or any other object in a closed orbit around the sun ... is greatest
when it's closest to the sun, at the point in its orbit known as "perihelion".
For the earth, that happens in early January every year. In 2010, it happened at 00 GMT on January 3.
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!
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.

What speed does a rocket have to reach to get into space?
A rocket needs to reach a speed of about 17,500 miles per hour (28,000 kilometers per hour) to overcome Earth's gravitational pull and reach orbit in space. This speed is known as orbital velocity.
The velocity a rocket must reach to establish an orbit around earth is called?
The velocity a rocket must reach to establish an orbit around the Earth is called orbital velocity. It is the speed required for an object to overcome gravitational pull and maintain a stable orbit around the planet. The orbital velocity depends on the altitude of the orbit and follows Kepler's laws of planetary motion.
What are the orbital speeds of Jupiter's Galilean moons compared to earth's moon?
The orbital speeds of Jupiter's Galilean moons are significantly faster than Earth's moon. For example, Io, the innermost moon, has an average orbital speed of about 17.3 km/s, whereas Earth's moon has an average orbital speed of about 1 km/s. This difference is because Jupiter's stronger gravitational pull causes its moons to orbit at higher speeds.
Which planet has the greatest variation of orbital speed?
Mercury has the greatest variation of orbital speed among the planets in our solar system. This is because its orbit is highly elliptical, resulting in significant changes in its speed as it moves closer to or farther away from the Sun.
Which planets orbital speed is thirty kilometers per second?
The planet with an orbital speed of around 30 kilometers per second is Earth. Its average orbital speed around the Sun is approximately 29.78 kilometers per second.
When does the Moon travel more faster around the earth?
The Moon's orbital speed is greatest when it is at its closest approach to the Earth.
How does earth's varying orbital speed affect it's rotation?
The earth's orbital speed has no influence or effect on its rotation.
What speed does a rocket have to reach to get into space?
A rocket needs to reach a speed of about 17,500 miles per hour (28,000 kilometers per hour) to overcome Earth's gravitational pull and reach orbit in space. This speed is known as orbital velocity.
How is orbital speed determined?
Orbital speed of a satellite: v - orbital speed G - gravitational consatnt R - radius of earth h - height of orbit

Do mercury and earth travel at the same speed?
Nope. Mercury has an orbital velocity of 47.9km/s, whereas Earth has an orbital velocity of 29.8km/s.
Which planet has the greatest variation of orbital speed?
Mercury has the greatest variation of orbital speed among the planets in our solar system. This is because its orbit is highly elliptical, resulting in significant changes in its speed as it moves closer to or farther away from the Sun.
What is Pluto's speed of rotation?
Pluto's speed of rotation is approximately 6.4 kilometers per hour, making it one of the slowest rotating planets in our solar system. A day on Pluto lasts about 6.4 Earth days.
Which planets orbital speed is thirty kilometers per second?
The planet with an orbital speed of around 30 kilometers per second is Earth. Its average orbital speed around the Sun is approximately 29.78 kilometers per second.
What is the orbital speed of earth in kilometers per second?
About 30 km/sec
Why does venus take 225 days to revolve around the sun and earth takes 365 days?
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
