apogee
The point of farthest excursion is called the apoapsis, with the closest approach being called the periapsis or pericentre, though for different bodies, unique derivitive terms are used. For example, when we talk of object in orbit about the Earth we use perigee and apogee for closest and furthest positions. When we are talking about objects in orbit around the sun, such as the planets, we use perihelion and aphelion for closest and furthest approches.
The perihelion is the closest point to the Sun in the orbit of a planet.It is different for each planet based on the elliptical variation, but will always occur at the same point in each orbit.
I suppose you mean when the Moon reaches its highest point above the horizon. It mainly depends on where the Moon is in its orbit around Earth. For example, the Full Moon is seen when the Moon is opposite the Sun in the sky. So, Full Moon is highest around midnight. At New Moon, the Moon is highest in the sky around noon, because it's near the Sun in the sky. Actually you can't usually see it then, of course, because of the Sun. So, you can see the Moon at its highest at many different times depending on the phase of the Moon (which depends on where the Moon is in its orbit).
The highest point of anything is called the summit.
The point in the moon's orbit when it is furtherest from Earth is its apogee (app-oh-jee).
That point in the orbit of the moon which is at the greatest distance from the earth., Fig.: The farthest or highest point; culmination.

All the planets orbit in a perfect circle, so they always stay the same distance from the sun, except Pluto, which is why it is now a "Dwarf Planet".
The highest point on a fir is the treetop.

apsis
The highest point is its source in Zambia.
The highest point in the world is mt.Everest and the lowest point in the world is somewhere in Antarctica
That's the point in Earth's orbit called "perihelion".The point in the orbit that's farthest from the sun is "aphelion".

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 highest point: Zugspitze 2,963 m (9721ft).
