1863 Antinous /ænˈtɪnoʊəs/, provisional designation 1948 EA, is a stony asteroid and near-Earth object, approximately 2–3 kilometers in diameter.
It was discovered on 7 March 1948 by American astronomer Carl Wirtanen at Lick Observatory on the summit of Mount Hamilton, California.
The SU/Sq-type asteroid orbits the Sun in the inner main-belt at a distance of 0.9–3.6 AU once every 3 years and 5 months (1,240 days).
[citation needed] In the Tholen and SMASS taxonomic scheme, Antinous is characterized as a SU and Sq type, respectively, which are subtypes of the broader group of S-type asteroids.
[1] The Apollo asteroid has a rotation period of 7.46 hours and an albedo between 0.10 and 0.240,[1][6][7][11] This minor planet was named after Antinous from Greek mythology.
