An asteroid has a very small chance to hit Earth. What happens if it does?
Scientists say they expect the asteroid's future trajectory and impact probability to change as astronomers collect and analyze more data.
An asteroid could collide with Earth: What could happen if it hits, and should we worry?
An asteroid could hit Earth, but scientists are continuing to gather data to understand its trajectory and potential impact to Earth.
A "city-killer" asteroid has a slim chance to crash into Earth. Here's what to know.
"An asteroid this size impacts Earth on average every few thousand years and could cause severe damage to a local region," the European Space Agency said.
Why the Odds of an Asteroid Striking Earth in 2032 Keep Going Up (and Down)
NASA and European scientists explain how they calculate the probability of the space rock 2024 YR4 impacting our planet, and why it’s not yet time to worry.
Scientists taking 'active measures' for asteroid with slight chance of hitting earth.
YR4 has just above a 1% chance of crashing into Earth in 2032, which is why astronomers and space agencies are paying attention to it.
Chances of a big asteroid strike on Earth just doubled. Here’s why you shouldn’t be too worried.
By comparison, the asteroid that wiped out the dinosaurs and 70% of all other animal species on Earth around 65 million years ago was roughly 6 to 9 miles wide. Other notable impact events include one in 1908,
