Earth, asteroids threat? Venus may be hiding 'killer' asteroids

Because their orbits are unstable, a possibility exists that the asteroids could break off from their current trajectory and one day head on a collision course for Earth.

The Venusian space rocks are large enough to be considered "city killers," meaning they're large enough to decimate a populated area in the event of a collission.

But don't panic: The asteroids likely pose no immediate danger to Earth, but are a way for astronomers to learn more about detecting them.

A likely lurking around Venus could one day pose an "invisible threat" to Earth if left unchecked, astronomers have warned in new research.

The giant space rocks are believed to be traveling as the planet orbits the sun, eluding our detection by staying hidden in the sun's glare. Because their orbits are unstable, a possi
