Overview

  • Asteroids 2025 KH, 2025 KE1, and 2025 KC, ranging from bus- to house-sized, have safely passed Earth within distances of 687,000 to 120,000 miles.
  • Asteroid 387746 (2003 MH4), measuring 1,100 feet in diameter, is set to pass Earth at a distance of 6.68 million kilometers on May 24, 2025.
  • Despite its size and proximity, asteroid 2003 MH4 poses no immediate threat, with NASA monitoring its well-determined orbit closely.
  • Potentially Hazardous Asteroids (PHAs) are tracked due to their size and proximity to Earth, although the likelihood of impact remains extremely low.
  • NASA emphasizes the importance of planetary defense initiatives to refine asteroid trajectories and prepare for potential long-term risks.
