Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
Since then, increasingly distant planets have been reached, with probes landing on or impacting the surfaces of Venus in 1966 , Mars in 1971 (Mars 3, although a fully successful landing didn't occur until Viking 1 in 1976), the asteroid Eros in 2001 (NEAR Shoemaker), Saturn's moon Titan in 2004 , the comets Tempel 1 (Deep Impact) in 2005, and ...
