Japan will join a European project to observe the Apophis asteroid when it passes close to the Earth by providing the H3 ...

The chance of an unknown asteroid hitting Apophis off its current course at all was less than one-in-a-million. And the odds that such an impact would send it hurtling toward Earth in 2029 was ...

Apophis, also known as asteroid 99942, was once thought to be on a potential collision course with Earth. The near-Earth object is estimated to be about 1,100 feet (340 meters) and could cause ...

Apophis—an asteroid as wide as three football fields—has a slim chance of slamming into Earth in 2068. Before then, however, the object is scheduled to zip past us in an encounter that ...

Asteroid Apophis was discovered on June 19, 2004. (Image credit: UH/IA) A key topic of interest is the degree to which Earth's gravitational pull may distort Apophis during the 2029 close approach.

Apophis caused a stir when it was first discovered back in 2004. At that time, the asteroid's orbit was not known well enough to rule out an impact with Earth in 2029 or 2036.

The chance of an unknown asteroid hitting Apophis off its current course at all was less than one-in-a-million. And the odds that such an impact would send it hurtling toward Earth in 2029 was ...
