For accurate long-term ephemerides, please instead use our Horizons system.This orbit viewer was implemented using two-body methods, and hence should not be used for determining accurate long-term trajectories (over several years or decades) or planetary encounter circumstances.

56422 Mnajdra           Discovered 2000 Apr. 2 by J. Ticha and M. Tichy at Klet.
Mnajdra is a prehistoric temple complex built with large limestone blocks, located on the southern coast of Malta. The lower temple is full of significant solar alignments, observable at equinoxes and solstices, and thus was probably used as an neolithic astronomical observation or calendrical site.
