Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new ...

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 ...

This artist’s concept illustrates how tightly the three stars in the system called TIC 290061484 orbit each other. If they were placed at the center of our solar system, all the stars’ orbits would be ...

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, ...

Astronomers studying the distant reaches of our Solar System have identified an unusual trans-Neptunian object (TNO) locked in a rare orbital configuration with Neptune. The object, discovered through ...
