The odds that asteroid 2024 YR4 could hit Earth in 2032 recently spiked from a little more than 1% to 2.3% as more observations are made.

Here are today's general risks from asteroids or comets both tiny and very large. Importantly, even relatively small rocks can still be threatening, as the surprise 56-foot (17-meter) rock that exploded over Russia and blew out people's windows in 2013 proved.

On the world's first Asteroid Day, Nina Burleigh discovers that Nasa has already commissioned a team of 'planetary defenders' for whom the question is not if but when

YR is considered to be larger than the Chelyabinsk asteroid that struck Russia in 2013. Its shock wave was strong enough to injure 1,500 people.

NASA's Jet Propulsion Laboratory has declared a 1.6% chance that a large asteroid would strike the Earth when on Dec. 22, 2032.

A terrifying simulation video shows the scale of destruction that could occur if an asteroid hits Earth - as scientists predict impact within the next 10 years

Astronomers have captured a new image of the asteroid 2024 YR4, which now has a 1 in 48 chance of hitting Earth in 2032.

YR4 is between 50 and 90 meters in size, large enough to cause localized damage in the very unlikely event it impacts Earth. With its size and chance of impact, a gl

Scientists warn that asteroid 2024 YR4 has a 2.3% chance of striking Earth in 2032—a small but serious risk. Nicknamed a "city killer," this space rock could cause massive destruction if it hits. NASA is using the James Webb Telescope to refine its trajectory,

This stunning volcano footage is just a glimpse of nature’s power—imagine what a city-killing asteroid could do if it struck your home… A newly discovered asteroid, 2024 YR4, has jumped to the top of risk lists after triggering automated warnings in December.
