A solar eclipse is most likely to occur when (hint: list order of line up of the three objects).

A solar eclipse occurs when the moon gets between Earth and the sun, and the moon casts a shadow over Earth. A solar eclipse can only take place at the phase of new moon, when the moon passes directly between the sun and Earth and its shadows fall upon Earth's surface.

ok yes, but what is the question? as soon as you ask the actual question i will answer it. : )
