A transit of Mercury across the Sun as seen from Venus takes place when the planet Mercury passes directly between the Sun and Venus, obscuring a small part of the Sun's disc for an observer on Venus. During a transit, Mercury can be seen from Venus as a small black disc moving across the face of the Sun. A central transit may last up over 8 hours, although presently transits' durations rarely exceed 7 hours. There was no overlap among the three transits, however. Source
