The rock, which was once considered the most dangerous object in the universe with the explosive power of 84 Hiroshimas, will narrowly miss our planet in 60 years' time.
The satellite is moving much faster than the earth's surface, though, because it must cover much more distance in the same amount of time. A geosynchronous satellite is moving at about 3.07 km/sec. Lower orbits are much faster.The space shuttle at 300km is moving at more like 7.73 km/sec. For comparison, the earth's surface at the equator moves at a leisurely 0.46 km/sec. To obtain a circular orbit of this velocity around earth, you would need to be at an altitude of around 1.6 million km. geosynchronous satellite is moving at about 3.07 km/sec.
