A: The Pasiphaë group is a group of non-spherical moons of Jupiter that move in retrograde orbits and are believed to have a common origin.
Q: What is the range of semi-major axes of the Pasiphaë group?
A: The range of semi-major axes of the Pasiphaë group is between 22,800,000 and 24,100,000 km, which is the same range as the Carme group.
Q: What is the range of inclinations of the Pasiphaë group?
A: The range of inclinations of the Pasiphaë group is between 144.5° and 158.3°.
Q: What is the range of eccentricities of the Pasiphaë group?
A: The range of eccentricities of the Pasiphaë group is between 0.25 and 0.43.
Q: What are the core members of the Pasiphaë group?
A: The core members of the Pasiphaë group, listed from the biggest to the smallest, are Pasiphae, Sinope (two-thirds the size of Pasiphaë), Callirrhoe, Megaclite, Autonoe, Eurydome, and Sponde.
Q: What naming convention does the International Astronomical Union (IAU) use for retrograde moons?
A: The International Astronomical Union (IAU) reserves names ending in -e for all retrograde moons, including members of the Pasiphaë group.
Q: What is the significance of the Pasiphaë group having a common origin?
A: The fact that the members of the Pasiphaë group have a common origin implies that they were formed by a single event in the past, such as the breakup of a larger moon or a collision with another celestial body.
