1874 Transit of Venus chart, egress 2
1874 Transit of Venus chart, egress 2 (exterior contact). This transit took place on 8-9 December 1874. Such transits (where Venus passes across the Sun as seen from the Earth) are rare, occurring in pairs over 100 years apart. The 19th-century transits (1874 and 1882) saw expeditions to make observations on interior and exterior contact for both ingress (first contact) and egress (last contact). Locations included New Zealand, Australia, Japan, China, Hawaii, New Caledonia, Kerguelen, Mauritius, India, and the Dutch East Indies. The results helped establish the distances of Venus and the Sun, and hence the size of the solar system

EDITORS COMMENTS
This print showcases the 1874 Transit of Venus chart, specifically capturing egress 2 (exterior contact). The transit itself occurred on the remarkable dates of 8-9 December 1874. These transits, where Venus passes across the face of the Sun as observed from Earth, are exceptionally rare and only occur in pairs over a century apart. During the 19th century transits in both 1874 and 1882, numerous expeditions were organized to observe interior and exterior contacts for ingress (first contact) and egress (last contact). These expeditions spanned across various locations including New Zealand, Australia, Japan, China, Hawaii, New Caledonia, Kerguelen Island, Mauritius, India, and the Dutch East Indies. The data collected during these ambitious missions played a crucial role in determining distances between Venus and the Sun. Consequently, this information helped establish accurate measurements for sizing our solar system. This historical photograph offers us a glimpse into an era when astronomers meticulously planned their observations using charts like this one. With its intricate illustrations depicting planetary movements and precise timings marked along with different regions of interest such as Oceania and Asia cut out on circular projections; it serves as a testament to humanity's relentless pursuit of knowledge about our universe. This artwork is not just an astrophysical marvel but also represents significant milestones achieved through scientific exploration during that period.
