Two satellites initially share identical circular orbits of radius $r_0$ around the Sun, each with orbital speed $v$. At the same instant, each satellite receives a small impulse of magnitude $\Delta v \ll v$, but the directions differ. Satellite A receives an impulse pointing radially outward (away from the Sun). Satellite B receives an impulse pointing forward along its direction of motion. In each new orbit, where does the perihelion lie, measured as an angular displacement from the burn point in the direction of orbital motion?
