The Satellites that Surround Earth . ... Credit Copyright: P. C.-W. Fu A. Hanson ( Indiana ), P. Frisch ( Chicago ), NASA Explanation: Thousands of satellites orbit the Earth. ... One common type of orbit is geostationary where a satellite will appear to hover above one point on Earth's equator. Geostationary orbits are very high up -- over five times the radius of the Earth -- and possible only because the satellite orbital period is exactly one day. ... NASA Official: Jay Norris. ...

We have used spectra taken between 1992 and 1997 to derive the spectroscopic orbit of the eclipsing double-lined spectroscopic binary HD 197770. This binary has a period of 99.69 +/- 0.02 days and K amplitudes of 31.2 +/- 0.8 and 47.1 +/- 0.4 km s^-1 for components A and B, respectively. ... These images show two apparent shells centered on HD 197770, a bright 60 ЮМm shell with a 28' diameter and a larger (0.8d diameter) bubble-like feature. ... ADS ] .

Different types of satellite orbits have different uses: while the synchronous orbit is best for communication satellites, Lagrangian point orbits help monitor the solar wind before it reaches Earth. A low altitude polar orbit is widely used for monitoring the Earth because each day, as the Earth rotates below it, the entire surface is covered. ... A different choice was made for MAGSAT, orbited 1979-80 to survey the Earth's own magnetic field near its surface. ...
