You've set two different criteria ... the Earth's closest satellite is not the
oldest one. So you've asked two questions, and they have different answers:
1). The identity of the Earth's closest satellite changes frequently,
because the close ones don't last long.
2). The Earth's oldest satellite is the Moon.
The moon is called a satellite of earth because it revolves around the earth
Perihelion is when the Earth is closest to the sun.
The satellite, or moon, called "Luna" averages 238,800 miles distant from Earth.
Because it is a satellite - it stays in orbit around Earth. And it is natural - meaning not made by humans.

the oldest satellite is the HubbleMoon
The oldest is the moon, also called Luna.
At periapsis, that is, when it is closest to Earth in its orbit.
5800km /h and its the iss!
Both of those words refer to points in the orbit of an earth satellite ... the moon or any artificial satellite. Apogee . . . the point in the orbit where the satellite is farthest from the earth. Perigee . . . the point in the orbit where the satellite is closest to the earth.
The moon is called a satellite of earth because it revolves around the earth
Earth has one natural satellite, the moon, and numerous artificial satellites, the first of which was called Sputnik, which can deservedly be called Earth's second satellite.
Vanguard 1 was the 4th artificial Earth satellite launched. It was placed in orbit on March 17, 1958. Communication was lost in 1964. It remains the oldest man-made satellite still in orbit and as such is the oldest piece of space junk orbiting Earth
It is the moon.
