Could Earth be in danger from asteroids we can’t even see? Scientists have identified a hidden population of asteroids sharing Venus’ orbit — and they might one day threaten our planet. These Venus co-orbitals are nearly impossible to detect with ground-based telescopes because of their close proximity to the Sun. But new simulations reveal that some of them could drift into Earth’s path over thousands of years, carrying enough energy to cause devastating impact events.

In this video, we break down what these asteroids are, why they’ve stayed hidden, and how space-based missions like NASA’s NEO Surveyor could help us find them before it’s too late.

00:00There could be deadly asteroids hiding right next to Venus,
00:03and we can't see them coming.
00:05Scientists have discovered that a secret group of asteroids
00:08might be sharing Venus's orbit.
00:10They're called Venus co-orbitals,
00:12and because they orbit so close to the Sun,
00:14our telescopes here on Earth can't detect them.
00:17Now here's the scary part.
00:19Some of these rocks could be as wide as a football field,
00:22and simulations show their orbits are unstable.
00:25Over time, they could drift out of Venus's path and into Earth's.
00:29We're talking about potential impacts every few thousand years.
00:32Enough to carve a crater nearly three miles wide,
00:35and release hundreds of megatons of energy.
00:38The problem?
00:39Our ground-based telescopes won't see them
00:41unless the conditions are just right.
00:43And that's why scientists are urging space-based missions
00:46like NASA's NEOSurveyor to step in.
00:49So no, it's not a threat today.
00:51But it's a cosmic game of hide-and-seek we can't afford to lose.
00:54Because sometimes, the most dangerous things
00:57are the ones we can't see.
00:59The most dangerous things are the ones we can't see.
01:00The most dangerous things are the ones we can't see.
