A malfunctioning Soviet satellite, Kosmos 482, is expected to crash into Earth today after orbiting since 1972. Originally part of the Venera program to explore Venus, it failed to leave Earth’s orbit due to a rocket malfunction.

Weighing about half a ton, the probe is likely to fall over water or remote land. Experts say the odds of it landing in a populated area are “infinitesimally small.” Its exact re-entry point is uncertain because of its age and solar activity fluctuations.

According to Marcin Pilinski from the University of Colorado Boulder, “much of the object may survive re-entry, but it will likely be severely damaged on impact.” The satellite’s batteries and parachutes no longer work, and it’s expected to hit Earth at about 150 miles per hour.

Most of the spacecraft has already disintegrated, leaving a one-meter-wide, 1,000-pound spherical module. Under international law, any debris that remains will belong to Russia.

Dutch scientist Marco Langbroek predicts it could land anywhere between 52° north and 52° south latitude, covering regions that include London, Vienna, Philadelphia, Rio de Janeiro, and Sydney—though experts insist the risk to people remains extremely low.
