  9. Transit of Mercury - Wikipedia

    en.wikipedia.org/wiki/Transit_of_Mercury

    A transit of Mercury across the Sun takes place when the planet Mercury passes directly between the Sun and a superior planet. During a transit, Mercury appears as a tiny black dot moving across the Sun as the planet obscures a small portion of the solar disk. Because of orbital alignments, transits viewed from Earth occur in May or November.
