The Earth moves fastest along its orbit at its perihelion, when it's closest to the sun, around January 4, and slowest when it's at its aphelion, when it's farthest from the sun, around July 4.
elliptical.
Aphelion is 152,098,232 km (the distance when the Earth is furthest from the Sun in July) at that point it is moving slowest: 29,300 m/s. Perihelion is 147,098,290 km (in January when the Earth is closest to the Sun) the orbital speed is greatest: 30,300 m/s.
the suns gravitational pull is strongest because the earth is at its closest point to the sun.
The year.
The slowest-changing feature on Earth's surface is likely its tectonic plates, which move at a rate of a few centimeters per year. This movement can result in slow changes in topography and the creation of mountains or ocean basins over millions of years.
Earth's orbital velocity is slowest on July 5 because that is when Earth is at aphelion, its farthest point from the Sun in its elliptical orbit. At this point, the gravitational pull from the Sun is weaker, causing Earth to move more slowly in its orbit.

The year.
The cheetah from the plains of Africa
Mercury's year of 88 days is pretty short when compared to Earths 365 day year. The orbital period gets longer the further you go out. Neptune is the furthest planet out and takes nearly 165 years to go around the sun once.
Earths orbital period is approximately 365.256366 days, or just over a year. This slight excess is the reason we have leap years.
In astronomy, axial tilt, also known as obliquity, is the angle between an object's rotational axis and its orbital axis, or, equivalently, the angle between its equatorial plane and orbital plane. It differs from orbital inclination.
The Earths orbit is fairly un-eccentric when compared to the other planets, with only Neptune and Venus having more regular (less eccentric) orbits. The eccentricity of earths orbit is 0.0167, the closest to this is Neptune's, with a value of 0.00859
The Earths orbital distance from the sun is 147,098,290km (91,402,641 miles) at its closest (Perihelion).
