Antapex May 2026

Research into lunar "cold spots" indicates that higher impact rates on the leading (apex) hemisphere contribute to the more rapid fading of these features compared to those on the trailing (antapex) side [7].

Over long periods (e.g., 10 years), the Sun's movement provides a baseline that allows for the measurement of parallax shifts in quasars and other extragalactic objects, with the shift always directed toward the antapex [9]. 4. Recent Case Studies antapex

Studies of Saturn's satellites suggest that large craters (e.g., >20 km on Rhea) show clear apex-antapex asymmetry, while smaller craters do not, potentially indicating different populations of impactors (heliocentric vs. planetocentric) [1, 21]. 3. Observational Data and Parallax Research into lunar "cold spots" indicates that higher

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].
