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.
A geostationary orbit. In this orbit, the satellite orbits the Earth at the same rate that the Earth rotates on its axis, allowing the satellite to remain fixed over the same point on the planet's surface.
The moon's farthest point from Earth in its orbit is called apogee.
The point on Earth's orbit when it is farthest away from the Moon is called apogee. This is the position where the gravitational forces between the Earth and the Moon are weakest.
Any object in a closed orbit moves slowest when it's at the point farthest away from the central body.If the central body happens to be the sun, then the point in the orbit that's farthest from the sun iscalled "aphelion". The earth passes aphelion on July 3 or 4.
Perigee.
Earth's orbit is an ellipse; the Sun is at one of the ellipses focal points. (The other focal point has no astronomical significance.)
The distance actually depends on the orbit of the Earth and Moon, with 221,665 miles at the shortest point and 252,525 miles at the farthest point.

Which orbit would that be? The galactic orbit, the solar orbit, the local cluster orbit? From what viewpoint? Above or below the galactic plane, the planetary system plane, from the point of view of a different place in the local cluster than on earth itself?
Perihelion
Periapsis
A geostationary orbit. In this orbit, the satellite orbits the Earth at the same rate that the Earth rotates on its axis, allowing the satellite to remain fixed over the same point on the planet's surface.
Perigee is the opposite of appogee. Perigee is the point in the orbit of the moon at which it is nearest to the earth. Apogee the point in the orbit of the moon at which it is furthest from the earth.
The moon's farthest point from Earth in its orbit is called apogee.
That's the point in Earth's orbit called "perihelion".The point in the orbit that's farthest from the sun is "aphelion".
There is one single point in the Earth's orbit where it is closest to the sun. That point is called the "perihelion".
