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 closest neighbor to Earth in space is the Moon. It is Earth's only natural satellite, located about 384,400 kilometers away.
The moon is called a satellite of earth because it revolves around the earth
The definition of a satellite be it man made or natural is, a body that orbits the parent. The earth is a satellite of the sun, the moon is a satellite of the earth ans so are all the man made ones we put in space.
Perihelion is when the Earth is closest to the sun.
The satellite, or moon, called "Luna" averages 238,800 miles distant from Earth.
the oldest satellite is the HubbleMoon
The satellite that revolves around the Earth is called the Moon.
The closest planet to the Moon is Earth. The Moon is Earth's natural satellite and is closest to our planet in terms of distance.
At periapsis, that is, when it is closest to Earth in its orbit.
5800km /h and its the iss!

The Moon
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.
in the orbit of a planet there is a point called perihelion which is closest point to the sun and aphelion which is furthest from the sun . Moment of a planet in it's elliptical orbit reaches it's maximum in perihelion
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.
