Bill Gray, an astronomer who notes that although astronomy is his profession, he is reluctant to call himself a professional astronomer as he lacks a PhD, used his own software to pinpoint the time and location of the impact. The object, dubbed 2025-010D, is a SpaceX rocket booster that failed to burn up in the atmosphere after launching its payload and instead entered Earth orbit. According to Scientific American: Gray first noticed the collision course last September, but he says that while calculating the effects of gravity from Earth, the sun and the moon was straightforward, there was another variable that made things more complicated. The rocket booster was being hit by solar radiation pressure, which is caused by the photons blasted out of the sun. As those photons hit an object, they apply force. The amount is tiny, but it builds up over time.…
