Up to 3,750 pounds of the satellite could reach Earth’s surface.

There is a 1-in-2,000 chance someone will be struck by fragments of ROSAT on its way down, according to Germany.

The 2.4-ton spacecraft, Germany’s Roentgen Satellite (ROSAT), is expected to fall Oct. 22 or 23.

The satellite will break up into fragments, some of which will disintegrate due to intense re-entry heat. But studies predict that about 1.6 tons of satellite leftovers could reach the Earth’s surface. That’s nearly half ROSAT’s entire mass.
