Giovanni [a] Domenico Cassini, also known as Jean-Dominique Cassini (8 June 1625 – 14 September 1712) was an Italian (naturalised French) [1] mathematician, astronomer, astrologer and engineer. Cassini was born in Perinaldo , [ 2 ] [ 3 ] near Imperia , at that time in the County of Nice , part of the Savoyard state .
Cassini's laws provide a compact description of the motion of the Moon. They were established in 1693 by Giovanni Domenico Cassini, a prominent scientist of his time. [1] Refinements of these laws to include physical librations have been made, [1] and they have been generalized to treat other satellites and planets. [2] [3] [4]
However Cassini, Rømer's superior at the Royal Observatory, was an early and tenacious opponent of Rømer's ideas, [6] and it seems that Picard, Rømer's mentor, shared many of Cassini's doubts. [11] Cassini's practical objections stimulated much debate at the Royal Academy of Sciences (with Huygens participating by letter from London). [12]
The Panzano Observatory was an observatory in the village of Panzano about 3 kilometres (1.9 miles) to the NNW of the centre of the comune of Castelfranco Emilia, near Bologna, Italy, where Giovanni Cassini worked. It was built in the early 1640s by Cornelio Malvasia. [1]

Cassini's formula was discovered in 1680 by Giovanni Domenico Cassini, then director of the Paris Observatory, and independently proven by Robert Simson (1753). [1] However Johannes Kepler presumably knew the identity already in 1608. [2] Catalan's identity is named after Eugène Catalan (1814–1894). It can be found in one of his private ...
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.
