First you may want to decide what you mean with "fast" - velocity in km/hour? Angular velocity?
Both Jupiter and Saturn spin more than twice as fast as Earth (angular velocity). You may also want to check the rotation of Uranus and Neptune, they rotate faster than Earth, but not twice as fast.

The earth's highest orbital velocity occurs at the moment when the earth
reaches perihelion ... the point in its orbit where it is closest to the sun.
In 2010, that happened on January 3rd.

Just like every other mass in a closed orbit around a central body, the earth travels
fastest in its path around the sun when it's at the point in its orbit that's closest to
the sun ... the point called "perihelion". That happens in the first few days of January.

tjhat would depend on your frame of reference. If that frame of reference is the Sun, then when the Earth is at perihelion (closest to the Sun -around January 3) its angular velocity is greatest.
In its orbit, the Earth at perihelion moves around 110 000 kilometers an hour. That is about 8,5 times the diameter of the Earth or halfway to the moon (in just one hour)!
The earth's orbital speed is greatest at the point in the orbit where it's closest to
the sun. That point is called the "perihelion", and the earth passes it on the 1st
or 2nd day of January.
All planets follow elliptical orbits. Kepler's laws of planetary motion tell us that the planets are moving faster when they are closest to the Sun, and more slowly when they are further away.
In the case of Earth, there isn't a whole lot of difference. But the Earth is closest to the Sun about January 4 each year, and furthest away on July 4th.
When the Earth is closest to the sun. That point in the orbit is called
"perihelion". We pass it during the first few days in January.
(That's right. The Earth is closest to the sun in January.)
Earth is closest to the Sun around the 4th of July. During that time it's motion is the fastest but only by a small percent. The average speed of rotation is 30 kilometer per second.
Earth is closest to the Sun during perihelion around the 3rd of January every year.
Its speed varies between 30.287 and 29.291 km/s, according to Kepler's laws of planetary motion, and its angular speed also varies, and thus the Sun appears to move faster at perihelion (currently around January 3) and slower at aphelion a half year later (on the 4th of July).
The Earth's spin, or rotation on its axis gives us a day.
The sun's gravitational pull keeps the earth in orbit around it.
The path where a planet moves around the sun is called an orbit.
The average speed of the earth in orbit is around 30 km/sec or 108,000 km/h. The planet moves faster when it's closer to the sun and slower when it's further away, sweeping out equal areas in equal time.
it makes one orbit
The earth moves most rapidly in its orbit around the sun at perihelion, when it is closest to the sun. That occurs some time during the first few days of January.
The earth moves around the sun in a elliptical orbit.
A single Earth orbit is one time the Earth moves around the sun.
this path is called its orbit :)
The ORBIT of the Moon.
orbit!
The name of the path the earth takes around the sun is known as the orbit. The earth takes slightly over 365 to complete its revolution round the sun.
In its orbit around the Sun, the Earth moves at 30 km/second.
In its orbit around the Sun, the Earth moves at about 30 km/sec.
This is called its orbit. Strictly, the moon and the earth both orbit their common centre of mass. The path of the moon around Earth is elliptical orbit. It takes about 29 days to complete one orbit of earth by moon.
The Earth follows a (slightly) elliptical orbit around the Sun.
1 year.
