Earth’s gravity pulls everything toward the center of the planet. To stay in the earth’s orbit, the speed of a satellite must adjust to the tiniest changes in the pull of gravity.(人造卫星利用重力保持在轨道上。地球的引力把所有东西都拉向地球的中心。为了保持在地球轨道上运行,卫星的速度必须...

A satellite is an object in space that orbits around another. It has two kinds — natural satellites and artificial satellites. The moon is a natural satellite that moves around the earth while artificial satellites are those made by man. Despite their widespread impact on daily life, artificial...
12. Since the discovery in 1995 of the first "exoplanet" - a planet orbiting a star other than the Sun - more than 200 others have been found by ground-based observatories. 13. Until now the usual method of finding exoplanets has been to detect the "wobble" their gravity imparts on...
