The discovery of 433 Eros the second largest near Earth object, 1898.
443 Eros provisional designations 1898 DQ, is a stony and elongated asteroid of the Amor group and the first discovered and second largest near Earth object with a mean diameter of approximately 16.8 kilometres. Visited by the NEAR Shoemaker space probe in 1998, it became the first asteroid ever studied from orbit.
The eccentric asteroid was discovered by German astronomer Carl Gustav Witt at the Berlin Urana Observatory on 13 August 1898, and later named after Eros, a god from Greek mythology; the son of Aphrodite who is identified with the planet Venus.
Dynamical integrations suggest that Eros may evolve into an Earth-crosser within as short an interval as two million years, and has a roughly 50% chance of doing so over a time scale of 108 to 109 years. It is a potential Earth impactor, about five times larger than the impactor that created Chicxulub crater and led to the extinction of the dinosaurs.
Extra Note: Eros was named after the Greek god of love.
