The direction of motion significantly influences the frequency and velocity of cosmic collisions.
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]. antapex
For planets like Earth, this is the trailing side of the planet's orbital path around the Sun. 2. Antapex and Impact Dynamics For planets like Earth, this is the trailing
The antapex is a baseline for measuring large-scale cosmic shifts. Synchronously rotating moons (like Rhea and Iapetus) often
Synchronously rotating moons (like Rhea and Iapetus) often exhibit an apex-antapex asymmetry [1]. The leading hemisphere (apex) generally shows a higher density of large impact craters than the trailing hemisphere (antapex) because it "sweeps up" debris in its path [7].
