New simulations examine whether the seven planets in the TRAPPIST-1 system could host moons, showing that only small, close-orbiting moons could remain stable over long periods ...

In this video, we dive deep into the concept of circular orbits within the Three-Body Problem. Explore how gravity, motion, and complex interactions between three celestial bodies create fascinating ...

Legend has it that Isaac Newton had the moment of inspiration that would lead to his theory of gravity when, on a warm ...

All of the objects in our solar system are acted upon by forces. Forces are pushes or pulls. Every force has both a strength and a direction. Applying a force on something–like pushing a toy car–can ...
