(4928) Vermeer is an asteroid of the main inner belt , which was discovered by the Soviet astronomer Lyudmila Georgievna Karachkina on October 12, 1982 at the Crimean Observatory in Nautschnyj ( IAU code 095).
The asteroid's period of rotation was measured for the first time on September 9 and 10, 2010, at the Osservatorio astronomico della Regione Autonoma Valle d'Aosta in Nus -Saint-Barthélemy by the Italian astronomer Albino Carbognani with an 81 cm Ritchey-Chrétien-Cassegrain Telescope , and determined to be 3.687 (± 0.003) hours. Due to the short rotation period and the two long observation times, (4928) Vermeer could be used as a test object for the method of redshift measurement in 17 other asteroids.
The asteroid was on 1 September 1993 by Jan Vermeer designated to one of the most famous Dutch painter of the Baroque is.
