Perihelion
Yes, but negligible. Since the earth's orbit is an ellipse, the earth's velocity has a tiny component which is towards the sun during part of the year and away from the sun at other times.
The linear velocity of Earth is important because it determines the speed at which Earth travels in its orbit around the Sun. This velocity helps maintain the balance between gravitational pull and centrifugal force, keeping Earth in a stable orbit and ensuring that it completes its journey around the Sun in a year.

At perihelion, when the Earth is closest to the Sun, about January 4 each year.
On that date Earth is farthest away from the Sun.
Earth's velocity around the Sun changes slightly throughout a given year. This is because Earth's orbit is not a perfect circle, but an ellipse that deviates slightly from a true circle. When Earth is closest to the Sun, in early January (Jan. 04), its velocity is a bit higher that its average yearly orbital velocity. This point in Earth's orbit is called perihelion. Six months later, on or about July fourth, Earth is at aphelion, its farthest distance from the Sun for a given year. During this time, Earth's velocity is slower than the yearly average. Earth's average orbital speed is 107,200 km per hour, or 66,610 miles per hour. When Earth is closer to the Sun, it moves faster; and when farther from the Sun, a little bit slower than the average.
The amount of solar energy Earth receives in a year varies the greatest near the poles. This is because of the tilt of Earth's axis, which causes the angle of sunlight to change throughout the year, leading to more extreme differences in solar energy received in polar regions compared to equatorial regions.
If you measure the speed times the velocity in wich the earth turnes by day divide it by the year minus the seasones in a year and look it up some where in the internet you will get your answer because I really do not know I am just guessing.( reapeating what I learned in school) so I may be wrong...... :( sorry. measure the speed times the velocity as the earth turnes divided by the year and you will come up with some number which is going to be longer.
That depends on what you mean by the "greatest show on earth"; several things have been either formally or informally (i.e. nicknamed) as such over the years. See the related links for a few of them.
The relative velocity between the African and South American plates is about 2.5 centimeters per year. This movement is part of the broader process of plate tectonics, where the Earth's lithosphere is divided into several large plates that interact and move over the underlying asthenosphere.
