Two Massive Asteroids to Safely Pass Earth Within 42 Hours

Asteroid 2024 MK and 2011 UL21 offer rare observational opportunities during Asteroid Day 2024.

Asteroid 2024 MK, discovered just ten days ago, will pass within the Moon's orbit on June 29.
Asteroid 2011 UL21, one of the largest near-Earth objects, will fly by at a safe distance on June 27.
Both asteroids pose no threat to Earth but highlight the importance of monitoring near-Earth objects.
The European Space Agency's efforts in planetary defense include the upcoming Hera mission and Flyeye telescopes.
Asteroid Day commemorates the 1908 Tunguska event, emphasizing the need for continued vigilance against cosmic hazards.
