Antapex May 2026

The point from which the Sun appears to be moving away, situated roughly at R.A. 6h, Dec -30° [10].

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

In any system of motion, the is the "forward" direction and the antapex is the "rearward" direction. The point from which the Sun appears to

The Sun's motion toward its apex creates a pattern of proper motions where distant stars appear to drift toward the antapex over time [14]. Studies of Saturn's satellites suggest that large craters (e

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
