Although the collision has now been ruled out, Apophis will still perform an exceptionally close flyby of Earth that same year at a distance of 32,000 km from the surface. This event presents a unique...

A frozen orbit is an orbit chosen such that the effect of perturbations on (a combination of) the mean orbital elements is minimized. The concept first appeared in literature in 1978, and was applied that same year to the Seasat mission. This altimetry mission featured strict requirements on the accuracy of the altitude of the satellite above...

The existence and characteristics of periodic orbits (POs) in the vicinity of a contact binary asteroid are investigated with an averaged spherical harmonics model. A contact binary asteroid consists of two components connected to each other, resulting in a highly bifurcated shape. Here, it is represented by a combination of an ellipsoid and a...
