Oamenii de știință au crezut timp de 27 de ani că urmăresc asteroid. Ce au văzut când s-a apropiat de Pământ? • Newsweek România

For 27 years, scientists believed they were tracking an asteroid, but it turned out to be a dark comet. This discovery has significant implications for understanding near-Earth objects and their potential risks. The object, initially designated as asteroid 1998 SH2, exhibited non-gravitational movements indicative of cometary activity, such as gas sublimation. This finding suggests that dark comets may be more common than previously thought and could have played a role in delivering water to early Earth. The study emphasizes the importance of continuous monitoring of near-Earth objects to accurately identify their nature and potential threats.
