Elia Filippo Francesco Giuseppe Maria Millosevich (September 5, 1848, in Venice – December 5, 1919, in Rome), was an Italian astronomer.
He specialized in calculating the orbits of comets and asteroids, in particular 433 Eros.
He first studied at the University of Padua; his first papers, on the then-forthcoming 1874 and 1882 transits of Venus, attracted attention and got him the position of professor of nautical astronomy at the Reale Istituto di Marina Mercantile a Venezia (Venice Royal Institute of the Merchant Navy).
He published over 450 smaller and larger works, and a large number of single observations of planets and comets.
In 2004, the main-belt asteroid 69961 Millosevich, discovered by the Italian astronomers Piero Sicoli and Francesco Manca, was named in his memory.
Naming citation was published on July 13, 2004 (M.P.C.
