Orbital mechanics can be a bit counter-intuitive. We have to slow down an orbiting space craft to convert kinetic energy for gravitational energy. The orbital altitude is raised at its highest point ...

Learn how to calculate the Earth’s orbital speed using fundamental principles of orbital mechanics and gravity. This video walks through the key equations and physical reasoning that explain how Earth ...

Visualization of the Sun-Earth Lagrange points. Orbital mechanics is a fun subject, as it involves a lot of seemingly empty space that’s nevertheless full of very real forces, all of which must be ...

Annotation Designed to be used as a graduate student textbook and a ready reference for the busy professional, this third edition of "Orbital Mechanics is structured so that you can easily look up the ...

Orbital pursuit–evasion games represent a class of strategic interactions where spacecraft, operating under the laws of orbital mechanics, engage in a dynamic contest of manoeuvre optimisation.

Earth’s path around the Sun is not a fixed racetrack but a slowly shifting orbit, and those subtle changes have a long history of reshaping the planet’s climate. As astronomers refine how these ...
