Earth is more likely to encounter ISOs during the winter months when its orbital position aligns with the solar antapex [2, 3]. While the fastest objects approach from the solar apex, the overall volume of impacts can be higher from the antapex direction due to the relative orbital geometry [19]. In any system of motion, the is the
