An asteroid designated as 2024 MK is poised to make a close but harmless passage by Earth this weekend, offering skywatchers a rare opportunity to observe a celestial body of significant size in relatively close proximity to our planet.
The asteroid, first detected by a South African observatory just two weeks ago, is estimated to measure between 393 and 853 feet (120 to 260 meters) in diameter.
At its closest approach on Saturday morning, 2024 MK will pass Earth at approximately three-quarters of the distance between Earth and the moon. While this proximity is considered close in astronomical terms, it poses no threat to our planet.
NASA’s Center for Near-Earth Object Studies expert, Davide Farnocchia, contextualizes this event within the broader phenomenon of near-Earth asteroids. He notes that while smaller objects frequently pass by Earth, asteroids of this magnitude only do so approximately every 25 years, making this a noteworthy occurrence for astronomers and space enthusiasts alike.
The observation of 2024 MK presents several challenges for amateur skywatchers. Its rapid trajectory across the southern sky, combined with its relative dimness, necessitates the use of a small telescope and precise timing for successful viewing. Observers in the Southern Hemisphere are particularly well-positioned for this event, as the asteroid will appear higher in their night sky.
For those in the Northern Hemisphere, particularly in the United States, optimal viewing conditions may occur on Saturday night. Although the asteroid may appear less bright at this time, the absence of solar glare will facilitate easier observation.
This event serves as a precursor to an even more significant astronomical occurrence scheduled for April 13, 2029, when the asteroid Apophis will pass close enough to Earth to be visible to the naked eye from certain regions of Europe, Africa, and Asia.
