|
| When a neutron star binary coalesces, the rapidly spinning merged system is expected to form a spinning black hole, orbited momentarily by a torus of neutron-density matter. |
|
| If the Moon orbited Earth in exactly the same plane that Earth orbits the Sun, we'd get a solar eclipse every New Moon and a lunar eclipse every Full Moon. |
|
| National pride stopped Omega winning rights to be the official watch of China's first spaceman, who orbited the earth last year. |
|
| The body involved moved on the epicycle, and the epicycle's center orbited the earth. |
|
| But commutes are short precisely because the city has competing centres of gravity, each orbited by neighbourhoods, markets, offices and slums. |
|
| A perfectly symmetrical point-mass in empty space could be orbited by an infinitesimally small mass in a circular orbit. |
|
|
|
| In four hours, 52 minutes and 31 seconds they orbited the Earth three times. |

|
| Some of the rest condensed into smaller objects that orbited around the new Sun: the planets. |
|
| It orbited slowly on its axis, revealing nothing, but yet saying so much. |
|
| But the planets Mercury, Venus, Mars, Jupiter, Saturn, and the one comet then known, orbited the sun, not the earth. |
|
| It is also the sixth IX series satellite to be orbited by Europe's launcher, confirming Intelsat's full confidence in Arianespace. |
|
| He orbited the Earth more than 2,900 times, spent more than 230 hours exercising and conducted about 236 hours of scientific research. |
|
| This flight orbited the Earth in a circular trajectory at an altitude of 296 km and for most of the ten day mission. |
|
| Instead of orbiting the Sun, like most comets, however, this one had been captured by Jupiter's gravity and the rocky fragments now orbited the King of Planets itself. |
|
| Yoder's group made the bulge measurements by monitoring the motion of the Mars Global Surveyor spacecraft as it orbited the planet over the past 3 years. |
|
| My father and I stopped walking, and he orbited slowly until he faced us. |

|
| Satellites and small space stations orbited the planet, along with three moons, one of which was covered in domes and crossed with covered roads to make it somewhat habitable. |
|
| Jupiter is orbited by Io, a body wracked by intense volcanism, while Saturn's largest moon, Titan a body larger than the terrestrial planet Mercury exhibits a primitive atmosphere denser than that of Earth. |
|
| In either case, planets orbited their parent stars and weren't massive enough to trigger hydrogen fusion. |
|
| At our very next practice, while we orbited him, he casually chatted about the transits of Jovian planets. |
|
| Before Yuri Gagarin or John Glenn orbited the Earth, artist Chesley Bonestell was depicting what life would be like in orbit and which kind of space vehicles would be used. |
|
|
|
| In September 1987, an Ariane 3 orbited the Aussat K3 satellite. |
|
| Since a hydrogen atom consists of a lone proton orbited by a lone electron, liquid hydrogen is a target-rich environment for those seeking to understand the structure of protons. |
|
| As important, the same pattern is visible wherever AMS happened to be pointing as it orbited Earth. This sits nicely with the notion that dark matter is strewn more or less evenly across the universe. |
|
| When a star is orbited by a planet lying far from it, the center of mass lies farther out, enlarging the star's orbit and making it easier to observe. |
