7. Satellite Tracking Functions

Many low-orbit Earth satellites are visible to the naked eye, but to spot them requires a knowledge of exactly when to look. The window of opportunity is about two minutes wide and occurs at a time just after dusk or just before dawn.

The Mir Space Station is the best and brightest object to see. It can appear as bright as the brightest stars. A Space Shuttle can also appear as bright as Mir, but missions are relatively infequent.

Other satellites that sometimes appear bright are the Hubble Space Telescope (HST), the Upper Atmosphere Research Satellite (UARS), and the Cosmic Background Explorer (COBE).

Scientific Astronomer provides several functions for adding and analyzing the orbit of satellites. These functions are able to add comets and extra asteroids as well as objects in orbit around other planets or moons.
