2018 CB

The term "2018 CB" refers to a small near-Earth asteroid that passed very close to Earth on February 9, 2018. Discovered just days before its close approach by the Catalina Sky Survey, its estimated size was between 15 and 40 meters in diameter.

While its proximity raised some public interest and discussion about potential impact hazards, 2018 CB posed no actual threat to Earth. Its close approach provided scientists with an opportunity to study near-Earth objects and refine models used for predicting future asteroid trajectories.

The event served as a reminder of the ongoing efforts to detect and track potentially hazardous asteroids, highlighting the importance of planetary defense programs aimed at mitigating the risk of asteroid impacts. While 2018 CB itself was not a threat, similar-sized objects are frequently encountered and illustrate the necessity of continued vigilance and research in this field.
