The Cassini projection (also sometimes known as the Cassini–Soldner projection or Soldner projection [1]) is a map projection first described in an approximate form by César-François Cassini de Thury in 1745. Its precise formulas were found through later analysis by Johann Georg von Soldner around 1810. [2]
It was compiled by the Cassini family, mainly César-François Cassini (Cassini III) and his son Jean-Dominique Cassini (Cassini IV) in the 1700s. It was on a scale of one line to 100 toises, i.e. 1/86,400. The map was, for the time, a real innovation and a decisive technical advance. It is the first map to be based on a geodesic triangulation ...
New map projections are still being developed, university map collections, such as Perry–Castañeda Library Map Collection at the University of Texas, offer better and more diverse maps and map tools every day, making available for their students and the broad public ancient maps that in the past were difficult to find.

In the hours prior to Voyager 1's encounter with Io, the spacecraft acquired images for a global map with a resolution of at least 20 km (12 mi) per pixel over the satellite's leading hemisphere (the side that faces the moon's direction of motion around Jupiter) down to less than 1 km (0.6 mi) per pixel over portions of the sub-Jovian ...
Neith is a hypothetical natural satellite of Venus reportedly sighted by Giovanni Cassini in 1672 and by several other astronomers in following years. It was 'observed' up to 30 times by astronomers until 1770, when there were no new sightings and it was not found during the transit of Venus in 1761 and 1769. [1] [2]
