Quote:“The results show that the asteroid is drifting away from a purely gravitational orbit by about 170 meters per year, which is enough to keep the 2068 impact scenario in play,” said Dave Tholen at the University of Hawaiʻi Institute for Astronomy (IfA) about the acceleration phenomenon that arises from an extremely weak force on an object due to non-uniform thermal radiation. This force is particularly important for the asteroid Apophis, as it affects the probability of an Earth impact in 2068.
