'''25143 Itokawa''' is a Near-Earth object discovered in 1998 by [[w:Lincoln Near-Earth Asteroid Research|LINEAR]] project and named for the Japanese rocket engineer [[w:Hideo Itokawa|Hideo Itokawa]]. It was visited by the [[w:Hayabusa|Hayabusa]] spacecraft in September 2005.

'''1620 Geographos''' is a Near-Earth object discovered in 1951 by [[w:Albert George Wilson|Albert George Wilson]] and [[w:Rudolph Minkowski]] at [[w:Palomar Observatory|Palomar]] and is named in honor of the [[w:National Geographic Society]].
−
Itokawa is a Near-Earth object released by T1234 in the add-on 3D Asteroids in November 2014. Modeled as a 45 km body in an eccentric orbit of .28 with a Semimajor axis of about 1.3 AU, it is considerably larger than the actual Itokawa which is about 330 meters average diameter.
 
  
−
The hard landing surface is very much below the visual surface, anywhere from about 30 km to 100 km below. It is modeled at a elongated object with a rough surface.
+
Geographos was to be visited by the [[w:Clementine mission]], failed to reach the body.
