When does the earth reach its greatest orbital speed?

Answer 1

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.

Answer 2

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

Answer 3

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.

Answer 4

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.

Answer 6

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.

Answer 7

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.)

Answer 8

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.

Answer 9

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!

Answer 10

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.
