(5231) Verne is an asteroid of the main middle belt discovered on May 9, 1988 by the American astronomer Carolyn Shoemaker at the Palomar Observatory ( IAU code 675) in California . The asteroid had already been sighted on November 21, 1960 under the provisional designation 1960 WT at the Lowell Observatory in Arizona .

features

The asteroid has an average diameter of about 11 km. The light curve of (5231) Verne was determined several times, for example during observations between February 11, 2007 and May 13, 2008 by René Roy at the Geneva Observatory and by Brian D. Warner et al. 2009, whereby the rotation period could be determined as 4.32058 h.

(5231) Verne is a member of the Eunomia family, a group named after (15) Eunomia that is believed to include five percent of the main belt asteroids. The timeless (non- osculating ) orbital elements of (5231) Verne are almost identical to those of two smaller ones, assuming the absolute magnitudes of 15.2 and 16.6 compared to 11.9, asteroids: (117009) 2004 HX 63 and (343818) 2011 HZ 11 .

According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (5231) Verne assumed a bright surface, so it could, roughly speaking, be around trade an S asteroid . A relatively light surface was later confirmed with an albedo of 0.243 (± 0.021).

designation

(5231) Verne was named on February 15, 1995 at the suggestion of the former director of the University of London Observatory Michael Dwortesky after the French writer Jules Verne (1828-1905). In the dedication formulated by Dworetsky, Jules Verne's works From Earth to the Moon (1865), 20,000 Leagues Under the Sea (1870) and Journey Around the Earth in 80 Days (1873) were highlighted and mentioned that the Shoemakers and Dworetsky were great fans of the work of Jules Verne.

As early as 1961, a lunar crater on the southeastern back of the moon was named after Jules Verne: lunar crater Jules Verne . The lunar crater Verne, on the other hand, was named after the Roman first name Verne in 1976 .
