The Moon’s orbit around Earth is not perfectly circular. This orbit is essentially elliptical, meaning that the distance between the Moon and Earth is not uniform, the farthest point is called the “apogee” and the nearest point is called “perigee”.
“If perigee or apogee coincides with a new or full moon – times when the Earth, Moon and Sun are aligned – the nearest and farthest distances from the Moon also decrease or increase.”explains Timeanddate.
At the new Moon, the Moon is between the Sun and the Earth. At that time, people could not see the Moon because the part of the Moon facing the Earth was in darkness (From Earth, people could only see the part of the Moon that was facing the Earth).
