Asteroids around Venus, shown in the background above during a 2012 transit, are difficult to track because they fall inside Earth's orbit and are obscured by the sun's glare.

"The co-orbital asteroids of Venus are highly chaotic, with Lyapunov times of the order of 150 years," the authors explained. The Lyapunov time refers to how long an object's orbit takes to become ...

Venus's co-orbital asteroids are considered potentially hazardous asteroids (PHA) if they have "a minimum diameter of about 140 meters and come within 0.05 astronomical units (au) of Earth's orbit ...

Cosmos (or Kosmos) 482's orbit has slowly brought it closer to our planet since 1972, and now it's on the cusp of plummeting back to its home world.

Cosmos 482 separated into four pieces, with two pieces decaying in low Earth orbit within 48 hours and the remaining pieces remaining in higher orbit. It is thought that a malfunction during the ...
