Short description: Ancient Greek astronomer
Agrippa (Greek: Ἀγρίππας; fl. 92 AD) was a Greek astronomer. The only thing that is known about him regards an astronomical observation that he made in 92 AD.[1] Ptolemy writes that in the twelfth year of the reign of Domitian, on the seventh day of the Bithynian month Metrous, Agrippa observed the occultation of a part of the Pleiades by the southernmost part of the Moon.[2]
The purpose of Agrippa's observation was probably to check the precession of the equinoxes, which was discovered by Hipparchus.[3]
The lunar crater Agrippa is named after him.[4]
