- n. periapsis in orbit around Jupiter
Sorry, no etymologies found.
The craft is due to enter an elongated orbit about Jupiter, taking 11 days to loop within 4,300 km of Jupiter's equatorial cloud-tops at its low-point, or perijove, and a high-point, or apojove, some 2.7 million km further out, beyond the orbit of Callisto which is the farthest of Jupiter's four main moons.
A successful burn at perijove was all that mattered; they would have plenty of time to study mysterious black spots on the way home.
Even at perigee -- er, perijove -- it's much too high to be affected by atmospheric drag. "
