Herbert Raab (born January 24, 1969 in Linz, Austria) is an Austrian software engineer, amateur astronomer and discoverer of astronomical objects. He finished his studiedes of computer science at the Johannes Kepler University of Linz in 1995 as a graduate engineer. In 2012, he received the Master of Science in ''Management for Engineers'' at the LIMAK business school in Linz, where he also graduated as Master of Business Administration in 2013. He works as a software engineer in the field of commercial software.〔(LinkedIn page of Herbert Raab ).

Since 1990, he has been developing the widely used software ''Astrometrica'', which is used for astrometric and photometric analysis of images of asteroids and comets.〔(Astrometrica web page ).

These observations have significantly contributed to the subsequent prediction of the impact of this comet on the planet Jupiter.〔(IAUC 5800: Periodic Comet Shoemaker-Levy 9 (1993e) ).

Herald et al.: "New Double Stars from Asteroidal Occultations, 1971-2008" In: Journal of Double Star Observations, Vol. 6 No. 1, pp. 88 ((Online ))〕 In May 1996, asteroid 3184 Raab was named in his honor, following a proposal of Brian G. Marsden and Gareth V. Williams from the Minor Planet Center.〔Lutz D. Schmadel: ''Dictionary of Minor Planet Names'' (5th Edition), p. 264. Springer Verlag, Berlin/Heidelberg 2003, ISBN 3-540-00238-3〕 On April 4, 1997, Raab was presented the Gold Medal for Services to the Republic of Austria.〔(Recipients of Medals of Honour for Services to the Republic of Austria ) (German).
