NASA is using the James Webb Space Telescope to study asteroid 2024 YR4, which has a 1-in-43 chance of hitting Earth in 2032. The space agency aims to determine the asteroid's size and potential damage if it were to impact Earth.
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.
“It is very important that we improve our size estimate for 2024 YR4: the hazard represented by a 40 m asteroid is very different from that of a 90 m asteroid,” the ESA wrote. “In general, the brighter the asteroid, the larger it is, but this relationship strongly depends on how reflective the asteroid’s surface is,” ESA officials explained. “2024 YR4 could be 40 m across and very reflective, or 90 m across and not very reflective.”
