(2419) Moldavia is an asteroid of the main inner belt , which was discovered by the Soviet astronomer Lyudmila Tschernych on September 19, 1974 at the Crimean Observatory in Nautschnyj ( IAU code 095). The asteroid had already been sighted on April 26, 1952 under the provisional designation 1952 HS 2 at the McDonald Observatory in Texas and on March 14, 1955 (1955 EM) at the Goethe Link Observatory in Indiana .
The asteroid belongs 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. The timeless (non- osculating ) orbit elements of (2419) Moldavia are almost identical to those of the two smaller ones, assuming the absolute brightness of 17.3 and 18.0 compared to 13.4, asteroids (330280) 2006 SZ 288 and ( 465629) 2009 HC 38 .
According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), Moldavia was (2419) in a spectroscopic investigation by Gianluca Masi , Sergio Foglia and Richard P. Binzel with a subdivision of all investigated asteroids into C, S and V types assigned to the C asteroids .
The mean diameter of (2419) Moldavia was calculated to be about 6 km.
Several attempts have been made to determine the rotation period , first in 1995 at the Observatoire de Haute-Provence , where a rotation period of 2.412 hours (± 0.003) was determined. However, later observations by, for example, Brian D. Warner in 2009 could not confirm the result, so that it must be said that the results are not sufficient for a reliable determination.
(2419) Moldavia was named on December 1, 1982 after the Moldovan Soviet Socialist Republic .
