Examples for

Satellites

Since the launch of Sputnik 1 in 1957, the number of satellites that have been launched has risen to upwards of 30,000 objects. Track objects orbiting Earth using Wolfram|Alpha. Tracked objects include actively controlled satellites as well as space junk, comprised of expended rocket engines and abandoned or non-functioning satellites. Plot the orbits of the satellites around Earth, whether they are low-Earth (LEO), geosynchronous (GSO) or geostationary (GEO), and discover whether their paths are polar or equatorial.
