Sometimes called the Black Moon. There is no such moon.
Lilith as plotted here is the mean lunar apogee: the point in the Moon's orbit furthest from Earth, averaged to smooth its considerable wobble. It is a position in an orbit, not a thing in the sky.
A 'true' or osculating apogee also exists and moves quite differently, sometimes retrograde. Sources rarely say which they mean, which is a common source of disagreement between charts.
It completes a circuit in about nine years. Nothing occupies it, and no telescope will show it.
What it is
The Moon's mean apogee — the far point of the lunar orbit. A calculated point, not an object.
