From this vantage point, the satellites' orbits match the rotation of Earth, allowing them to hover over the same position.

The ship lifted, leveled, and banked to go on course for the trajectory that would take it into an orbit matching Heimdall's.

Then two astronomers - the German, Johannes Kepler, and the Italian, Galileo Galilei - started publicly to support the Copernican theory, despite the fact that the orbits it predicted did not quite match the ones observed.

Every time our orbits have matched, there has been someone else in the CARM.

With your present course, speed, and position compute the cheapest orbit to match with Terminal's.

What is even more remarkable, Dr. Spurny said, is that the orbit of this rock matches that of the first meteorite discovered in this way, in 1959.

These individuals have watched how closely its orbit matches that of Tiangong.

The resulting irregular orbits match well with the observed populations' semimajor axes, inclinations and eccentricities, but not with their size distribution.

Its orbit matches the expected properties of that of an object in the Arjuna-class.

When William Herschel discovered Uranus in 1781, the planet's orbit matched the law almost perfectly, leading astronomers to conclude that there had to be a planet between the orbits of Mars and Jupiter.
