A relatively small asteroid, designated 2023 BU, will make a close but safe approach to Earth on Saturday, January 21st. The asteroid is estimated to be approximately 36 feet (11 meters) wide and will pass within 2,200 miles (3,540 kilometers) of the Earth’s southern tip – closer than many communication satellites. While this is a close approach, NASA confirms there is no risk of impact. Astronomers and stargazers with small telescopes may be able to observe the asteroid as it speeds past. The event presents a rare opportunity for observation, though optimal viewing conditions will depend on location and weather. This close approach is being closely monitored by NASA’s Jet Propulsion Laboratory as part of its ongoing planetary defense efforts.
