NEAR (USA) 17-Feb-96 Delta II 1.125 kg The NEAR space probe entered orbit around (433) Eros on Feb 14, 2000. Landed on Eros on Feb 14, 2001 at 1944:35 UTC at location 35S 279W. First landing from a probe on a Asteroid. Signals continued to be received from NEAR hours after the landing, confirming that it survived the 2m/s impact.

This is the last image of asteroid 433 Eros received from NEAR Shoemaker. Taken from a range of 120 m (394 feet), it measures 6 m (20 feet) across. What we can see of the rock at the top of image measures 4 m (12 feet) across. The streaky lines at the bottom indicate loss of signal as the spacecraft touched down on the asteroid during transmission of this image.
This was the first time a spacecraft landed on an asteroid.
