The Moon appears as a thin crescent when it is close to solar conjunction, which is better known as new moon. Simulated image courtesy of Tom Ruen.

An object is said to be at solar conjunction when it makes its closest approach to the Sun in the sky.

The planets are typically lost in the Sun's glare and impossible to observe for a few weeks when they pass solar conjunction. Mercury can reappear within only a few days, since it moves around its orbit so quickly that it can pass from solar conjunction to maximum elongation in less than a month.
