James Webb telescope takes emergency look at 'city-killer' asteroid 2024 YR4 ahead of close encounter in 2032
- The James Webb Space Telescope (JWST) observed asteroid 2024 YR4, a 'city-killer' asteroid approaching Earth and the moon in 2032.
- JWST's observation revealed that the asteroid may be larger and rockier than previously thought, but it poses no threat to Earth in 2032.
- There is a 2% chance that asteroid 2024 YR4 could collide with the moon in 2032, based on JWST data.
- Astronomers discovered asteroid 2024 YR4 in December 2024, estimating its size to be about 180 feet in diameter.
- The asteroid's trajectory crosses Earth's path, potentially endangering the planet if a collision were to occur.
- JWST's infrared sensors were crucial in studying the asteroid's size and composition, offering insights not available through ground-based telescopes.
- Despite some uncertainties, NASA confirmed a 0% chance of Earth impact by asteroid 2024 YR4 in 2032.
- The upcoming second round of JWST observations in May will provide further details on the asteroid's trajectory and likelihood of hitting the moon.
- While a lunar impact by the asteroid may occur in 2032, it does not pose a threat to Earth and could offer a unique research opportunity.
- Scientists are hopeful for a moon impact as it would allow studying the formation of a lunar crater by a known asteroid for the first time.
