Kosmos-482, which was headed to Venus, is expected to re-enter Earth’s atmosphere by the end of this weekend. Experts don’t yet know where it may come down.

Launched in 1972, the failed Venus probe has been stuck in Earth orbit ever since. Now it's hurtling back down to Earth.

A piece of space junk called Cosmos 482 is unlikely to pose a threat to people or property. But space experts say it highlights the need to stay vigilant.
