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

The antapex is not merely a "shadow" of the apex but a distinct region of interest for predicting interstellar impacts and understanding the geological history of tidally locked satellites [3, 25]. Future surveys, such as those by the APEX Telescope or Gaia , will continue to refine the celestial coordinates and physical implications of this trailing point in space [13, 24]. References antapex
