The mission was completed in 81 revolutions of the Earth and traveled 2.2 million miles.

Annual aberration is due to the revolution of the Earth around the Sun.

This flight made three revolutions of the Earth and lasted for 4 hours, 52 minutes and 31 seconds.

They successfully completed 56 experiments, 26 science demonstrations, 15 subsystem detailed objectives, and 13 student investigations during their 1,214 revolutions of the earth.

The words Galileo was supposed to have muttered after recanting before the Inquisition his belief in the revolution of the earth around the sun.

On their 45th revolution of the Earth, the crewmen fired the retrofire rockets that slowed them down so that they would reenter.

On each revolution of the Earth the craft would thus reach the higher northern latitudes of Europe and the Soviet Union.

Copernicus saw the futility of the arguments by which Ptolemy had endeavoured to demonstrate that a revolution of the earth was impossible.

Because of the revolution of the Earth about the Sun, the Sun seems to move from west to east against the back- ground of the stars.

The flight director decided that they would have to remain in orbit an extra day (a full revolution of the Earth), so they could determine what the problem was.

You only know the direction of the magnetic north pole, which may differ from the geographic north pole - the axis of revolution of the earth.

Seasons result from the yearly revolution of the Earth around the Sun and the tilt of the Earth's axis relative to the plane of revolution.

But for all these effects, the spin induced by the Plattnerite was of a different quality from the spinning of atop, or the slow revolution of the earth.

Eustachio Manfredi provided "the first demonstration, though unsought, of the revolution of the Earth around the Sun, and thus the reality of a heliocentric system".

Days and years are unique among units of time measurement, of course, with their basis in the rising and setting of the sun and the revolution of the Earth around it.

"The Smoky God," therefore, with each daily revolution of the earth, appears to come up in the east and go down in the west, the same as does our sun on the external surface.

With the development of the atomic clock, it was decided to use atomic clocks as the basis of the definition of the second, rather than the revolution of the Earth around the Sun.

The time taken to complete one revolution of the Earth is decreasing over aeons of time but at the moment it is, give or take the odd second, 24 hours; this defines the solar day.

The discovery was proof of a heliocentric model of the universe, since it is the revolution of the earth around the sun that causes an apparent motion in the observed position of a star.

It was clearly impossible to suppose that movements of this kind could be mere apparent displacements, arising from the annual shift in our point of view, in consequence of the revolution of the earth.

Then every billion years of Earth history would correspond to about twenty-four days of our cosmic year, and one second of that year to 475 real revolutions of the Earth about the sun.

Mark thought that Dimble was reading his mind and seeing there his certainty that he had no more power of calling Miss Hardcastle to account than of stopping the revolution of the Earth.

In the years following its launch, the small satellite has made more than 196,990 revolutions of the earth and traveled 5.7 billion nautical miles, the distance from Earth to beyond the dwarf planet Pluto and halfway back.

"But remember, the prediction uncertainties currently are on the order of one or two or even three days and Phobos-Grunt is making one full revolution of the Earth every 90 minutes - about 16 orbits a day.

The slow wobble of the earth's spin axis on the celestial sphere is independent of the diurnal rotation of the Earth on its own axis and the annual revolution of the earth around the sun.
