NASA is closely monitoring asteroid 2026 KC1, which is set to pass Earth on Friday at a speed of 45,522 mph. This bus-sized asteroid, measuring about 27 feet across, will make its closest approach at a distance of 304,000 miles. On the same day, several other asteroids will also pass by, including 2026 KF, which is plane-sized and will come within 408,000 miles, and 2026 JE1, another bus-sized rock, passing at 694,000 miles. NASA notes that small asteroids like these typically impact Earth every 10 years, but they rarely pose a threat to life, often resulting in bright fireballs and sonic booms without significant damage. Larger asteroids, such as those measuring 160 feet or more, can cause local devastation and strike Earth approximately every 1,000 years. Notably, asteroid 2024 YR4 has a 3.1% chance of hitting Earth in 2032, although recent calculations indicate it may collide with the moon instead. This highlights the ongoing need for monitoring near-Earth objects to assess potential threats.
