As best as anyone can tell, if any hazardously sized asteroid were to hit Earth in the relatively near future, it would most likely be 2024 YR4, a 130-to-300-foot rock that’s essentially the same size as the asteroid that exploded over Siberia.

A dive into probabilities, asteroid impact modeling, and what sort of damage an approximately 180-foot asteroid could cause on Earth.

NASA is monitoring a recently discovered asteroid called the 2024 YR4, which is around 150-300 feet wide and is the most hazardous space rock detected in more than 20 years. Astronomer and space scientist Dr.

Astronomers will use the Webb telescope to closely monitor the size and trajectory of an asteroid that has a slim chance of striking Earth in 2032.

Astronomers have been given access to the James Webb Space Telescope to assess the threat posed by asteroid 2024 YR4, which has a one-in-43 chance of hitting Earth in 2032

Astronomers have been granted emergency access to the James Webb Space Telescope to study an asteroid that poses a potential threat to Earth. The space rock, known as 2024 YR4, currently has a 2.3 per cent chance of colliding with our planet in 2032.

Will it help stave off a potential Armageddon? NASA is training humanity’s most powerful telescope on a “city-killing” asteroid to determine whether or not we need to brace for deep impact. Dubbed 2024 YR4,
