An artificial intelligence algorithm designed to help astronomers spot potentially dangerous, potentially Earth-bound asteroids has made its first discovery. The asteroid was spotted on July 18, 2023, and has been designated 2022 SF289. It is expected to pass within 140,000 miles of the Earth - well inside the Moon's orbit. At that range, it's been designated a Potentially Hazardous Asteroid (PHA). At 600 feet wide, if it impacted Earth it would hit with the explosive power of a 250-megaton nuclear bomb and leave a crater nearly 2 miles wide, according to calculations by Imperial College London academics. Fortunately, its path doesn't seem to take it on a collision course anytime soon - nor does any known PHA for the next 100 years. The discovery was made by HelioLinc3D, a program developed to aid the Vera C Rubin Observatory in Chile with its future Legacy Survey of Space and Time (LSST) mission. Since the observatory is still under construction, however, HelioLinc3D made the
