Astronomy
Roche Limit Calculator
Find the critical orbital distance inside which a satellite is torn apart by tidal forces. Use it to understand ring formation, comet disruption, and satellite stability around planets.
Fill in the required fields to see your result.
Astronomy
Galactic Year Calculator
Calculate how long it takes a star or object to complete one full orbit around the galactic center, given its orbital radius and velocity. Ideal for visualising cosmic timescales in astrophysics and astronomy coursework.
