The Moon crosses the plane of Earth's orbit twice in each complete orbit. |
|
What the high court has done, however, is to at least bring the torturers within the orbit of the law, subject to some form of accountability and judicial restraint. |
|
Commenting on the polls is not within the orbit of this bill. |
|
We continued to orbit until our two remaining wingmen joined. |
|
In truth, Bohr's atom, in which electrons orbit around a dense nucleus like planets around the sun, had already been largely envisaged by Rutherford. |
|
The noise had sent the stadium into orbit and Dublin just needed another score or two to fix Tyrone with a stare and make them think that losing was a possibility. |
|
In fact, all the stars are moving, in orbit around the galactic center and also shifting relative to each other with their own peculiar velocity components. |
|
The orbit injection by the Ariane rocket used to launch Rosetta was so accurate that only a small amount of fuel was needed to make some tiny corrections. |
|
An inner planet that did manage to stay in orbit would have its path elongated by the interaction, subjecting the body to huge temperature swings. |
|
Holst's figurant represents humanity exposed to the occult powers of the unfixed stars as they orbit through the twelve astrological houses of the zodiac. |
|
|
Long-term changes in the Earth's orbit are believed to cause a redistribution of insolation across both hemispheres, and these changes, in turn, lead to changes in climate. |
|
If a CME erupts on the side of the Sun facing Earth, and if our orbit intersects the path of that cloud, the results can be spectacular and sometimes hazardous. |
|
The particles in a low earth orbit may be numerous, but mainly they consist of parts that burnt and broke up upon re-entry, and are thus just small particles and flakes. |
|
Incredible temperatures would have occurred as the sun, the nine known planets, and the thousands of other bodies that orbit the sun gradually formed. |
|
During the encounter, one is thrown into the eccentric orbit and remains in the Solar System while the other is ejected into interstellar space where it wanders forever. |
|
He was also able to give greatly improved data for the orbit of Venus, finding better values for the radius of the orbit, its eccentricity and inclination to the ecliptic. |
|
Three special satellites located in geostationary orbit above Europe transmit a GPS-like signal that improves the GPS accuracy down to 1 to 2 metres. |
|
The comet made no reappearance and again Lexell correctly deduced that Jupiter had changed the orbit so much that it was thrown far away from the Sun. |
|
When it is revived at the end of the eighteenth-century by the English Della Cruscan poets, the tradition gains a new life in the orbit of the romantic movement. |
|
Although it poses no danger at all to the Earth at the moment, that could change if its orbit around the sun is deflected by the gravitational pull of a nearby planet. |
|
It was time to expand beyond the gravitational orbit of New York. |
|
When small-amplitude surface gravity waves progress in deep water, all the fluid particles are observed to orbit in circles within the depth of wave influence. |
|
When the jet was stable, we began a wide, right-hand turn toward land and set up an orbit about 20 miles northeast of Oceana to adjust gross weight. |
|
The first law states that the orbit of a satellite is an ellipse, and that one of the foci of the ellipse must be located at the centre of the Earth. |
|
The left orbit was medially compressed, and exophthalmos had occurred. |
|
Described in the same coordinate system as the earth's orbit, the moon would appear to be swinging around the earth on an orbit still bent towards the sun in every point. |
|
Apparently, the solid-on period for slaving just prior to retrofire brought the gyros back up to orbit attitude, because they corrected very nicely during that period. |
|
During an emergency that ratio could be allowed to drop to 8.5 people per orbit. |
|
Carlisle writes that the Air Force would want a crew ratio of 10 to one for each drone orbit during normal everyday operations. |
|
Astronomers using telescopes on Mauna Kea have found an extremely rare quartet of stars that orbit each other within a region smaller than Jupiter's orbit round the Sun. |
