(3184) Raab is an asteroid of the main belt , which on 22 August 1949 by the South African astronomer Ernest Leonard Johnson , from the Union Observatory ( IAU code 078) in Johannesburg from, was discovered.
The asteroid was named in May 1996 at the suggestion of Brian Marsden and Gareth V. Williams after Herbert Raab , an Austrian software engineer, amateur astronomer and developer of the Astrometrica software .
From observations with the WISE space telescope , the diameter of the asteroid was determined to be 19.3 kilometers and the albedo to be 0.05. Due to the low albedo, it can be assumed to belong to the C-type asteroids .
