SUMMARY

The discussion focuses on calculating the angular separation between the moons Styx and Nix of Pluto 28 days after they align on the same side. Given that the mass of Nix is 5 x 10^16 Kg and its orbital radius is 48,675 Km, while Styx has an orbital period of 20 Earth days, the angle traveled by Styx in 28 days can be determined using its orbital period. The calculation for Nix's angle involves understanding its orbital dynamics relative to Styx's position.

PREREQUISITES

Understanding of orbital mechanics and angular motion
Knowledge of Kepler's laws of planetary motion
Familiarity with basic trigonometry and angular calculations
Ability to perform calculations involving mass and orbital radius

NEXT STEPS

Please help I am not sure of how to work this out

The angular separation between Styx and Nix 28 days after they are in line with each other on the same side of Pluto.

Mass of Nix = 5*10^16 Kg
Orbital Radius of Nix = 48675 Km
Orbital period of Styx = 20 Earth days
