NASA Captures Detailed Images of Two Asteroids During Close Flybys

Recent radar observations reveal a binary system and surface details of near-Earth asteroids 2011 UL21 and 2024 MK.

Asteroid 2011 UL21, nearly a mile wide, was found to have a small moonlet orbiting it.
The asteroid passed Earth at a distance of 4.1 million miles, posing no immediate threat.
Asteroid 2024 MK, discovered just 13 days before its closest approach, came within 184,000 miles of Earth.
NASA's radar images of 2024 MK show detailed surface features, including ridges and boulders.
These observations provide valuable data for planetary defense and understanding asteroid formation.
