Asteroid Alinda could collide with Earth as big as Manhattan

On January 8, 2025, the asteroid (887) Alinda made its closest approach to Earth in decades, coming within 7.6 million miles, about 32 times the average distance between Earth and the Moon. This massive asteroid, which is approximately 2.6 miles wide, is notable for its size and rarity, as only a few asteroids of such dimensions are expected to pass within 15 million kilometers of Earth until 2200. The altitude of the asteroid's closest approach represents a significant event for both amateur and professional astronomers alike. Alinda is currently in the constellation Gemini, which is visible in the Northern Hemisphere after dark, providing a unique opportunity for skywatchers. Astronomers, including Gianluca Masi of the Virtual Telescope Project, have stated that Alinda will reach a peak brightness of magnitude 9.4 this weekend, requiring basic binoculars or a small telescope for viewing. The asteroid poses no threat to Earth and is being observed through a free livestream offered by the Virtual Telescope Project. Events of this magnitude are rare, making Alinda's flyby a highlight for the astronomical community. According to NASA, neither Alinda nor any known asteroid presents a danger to Earth for at least the next century, reassuring the public about the asteroid's harmlessness while also emphasizing the scientific value of such celestial events. Amateur astronomers excitedly anticipate the moment the asteroid can be seen from their backyards, blending the realms of science and public interest in astronomy. The next similar opportunity to observe a large asteroid will not occur until 2087, making the current event particularly significant for those interested in astronomy.
