For a time he remained crouching, and when at last he looked out again the little town was very small and travelling, with the rest of lower Germany, in a circular orbit round and round the car--or atleast it appeared to be doing that.
If a small planet also maintained a circular orbit, it would be even more hospitable to life, as it would support a stable climate year-round.
If the Moon were in a perfectly circular orbit, a little closer to the Earth, and in the same orbital plane, there would be total solar eclipses every single month.
In September 2032 the spacecraft will be inserted into polar orbits around Ganymede starting with elliptical and high altitude (5000 km) circular orbits followed by a phase with a medium altitude (500 km) circular orbit and by a final phase with low altitude.
Arianespace will deliver the O3b satellites into a circular orbit at an altitude of 8062 km with the latest Soyuz launch from the Guiana Space Center in French Guiana, an orbit that is four times closer to the earth than traditional geostationary satellites, providing O3b customers with substantial performance benefits due to lower latency or delay.
Launched as GRAIL A and GRAIL B in September 2011, the probes, renamed Ebb and Flow, operated in a nearly circular orbit near the poles of the moon at an altitude of about 34 miles (55 kilometers) until their mission ended in December 2012.
He said that both satellites are positioned at what's called Geostationary Earth Orbit (GEO), a circular orbit 35,786 kilometres above the equator that follows the direction of the earth's rotation.
In order to use this restriction, one assumes that the orbiting body is at or near its QCM equilibrium orbital radius r and that the orbital eccentricity [member of] is low so that our nearly circular orbit approximation leading to these particular equations holds true.
With its circular orbit inclined 20-degree to the Equator, the satellite
