Learn how geosynchronous orbits work and how to calculate the required orbital altitude. This video walks through the physics and equations that link orbital period, gravitational force, and ...

Great question! Assuming you’re referring specifically to the orbital period — in other words, how long comets take to make one revolution around the Sun, or a cometary “year” — according to basic ...

Does orbital motion really follow a simple mathematical law? 🛰️ This video shows how to verify Kepler’s Third Law for circular orbits, connecting orbital period and radius through gravitational ...

Astronomers from the University of Warwick have observed an exoplanet orbiting a star in just over 18 hours, the shortest orbital period ever observed for a planet of its type. It means that a single ...

Simple axioms can seem too simple. That was the case for aerospace engineer Max Fagin, when he encountered the rule of thumb that orbit at the surface level of rocky planets takes two hours. Dubious, ...
