(39529) Vatnajökull is an asteroid of the main inner belt , which was discovered on November 3, 1989 by the Belgian astronomer Eric Walter Elst at the La Silla Observatory of the European Southern Observatory in Chile ( IAU code 809).
Mean distance from the Sun ( major semiaxis ), eccentricity and inclination of the orbit plane of the asteroid correspond roughly to the Vesta family , a large group of asteroids named after (4) Vesta , the second largest asteroid and third largest celestial body in the main belt. According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (39529) Vatnajökull assumed a bright surface, so it could be roughly seen be an S asteroid , not a V asteroid.
(39529) Vatnajökull was named on October 8, 2014 after Vatnajökull , the largest glacier in Iceland .
