Views in Rodriguez of the transit of Venus. The 1874 transit of Venus took place on December 9, 1874 (01:49 to 06:26 UTC). There were five official British expeditions or observation sites. One expedition travelled to Hawaii, with two others sent to the Kerguelen Archipelago in the far southern reaches of the Indian Ocean, and Rodrigues, an island further north in the Indian Ocean, near Mauritius. A fourth expedition went to a site near Cairo in Egypt, and the fifth travelled to a site near Christchurch in New Zealand. Several of the expeditions included auxiliary observation stations that were constructed in addition to the main observation sites. A transit of Venus across the Sun takes place when the planet Venus passes directly between the Sun and Earth (or another planet), becoming visible against the solar disk. During a transit, Venus can be seen from Earth as a small black disk moving across the face of the Sun. Venus transits are historically of great scientific importance as they were used to gain the first realistic estimates of the size of the Solar System.
