List of landing ellipses on extraterrestrial bodies



This is a list of the projected landing zones on extraterrestrial bodies. The size of the ellipse or oval graphically represents statistical degrees of uncertainty, i.e. the confidence level of the landing point, with the center of the ellipse being calculated as the most likely given the plethora of variables. Their accuracy has improved from the early attempts in the 1960s; active research continues in the 21st century.
