(224831) Neeffisis is an asteroid of the main inner belt located between Mars and Jupiter .

It was discovered on November 27, 2006 by the German amateur astronomers Rainer Kling and Erwin Schwab from the Hans-Ludwig-Neumann-Observatory ( IAU-Code B01) on the Kleiner Feldberg in Taunus . This was the first time an asteroid was discovered by this observatory.

The asteroid was named on September 23, 2010 from a combination of the names of Christian Ernst Neeff (1782–1849), a German medic and physicist, and the ancient Egyptian goddess Isis . Neeff was a co-founder and first chairman of the Physikalischer Verein - Society for Education and Science , which runs the Hans-Ludwig-Neumann-Observatory. Isis adorns the club's logo. Already discovered in 1912 (728) Leonisis was named from the combination of the name Isis and a chairman ( Leo Gans ) of the Physikalischer Verein.
