Eros (minor planet designation: (433) Eros), provisional designation 1898 DQ, is a stony and asteroid of the Amor group and the first discovered and second-largest near-Earth object with an elongated shape and a mean diameter of approximately 16.8 kilometers. Visited by the NEAR Shoemaker space probe in 1998, it became the first asteroid ever studied from orbit around the asteroid.
The asteroid was discovered by German astronomer C.G. Witt at the Berlin Observatory on 13 August 1898 in an eccentric orbit between Mars and Earth, and later named after Eros, a god from Greek mythology; the son of Aphrodite, who is identified with the planet Venus.
