Scientists have identified the Bennu asteroid threat as the highest single-date impact probability for any known asteroid.

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 ...

Giant mirrors in space have been a staple of science fiction for decades. But so far, there's been very little work looking ...

Tracking exoplanets via orbital mechanics isn't easy. Plenty of variables could affect how a planet moves around its star, and determining which ones affect any given exoplanet requires a lot of data ...

Japan’s Hayabusa2 spacecraft is set to fly past near-Earth asteroid (98943) Torifune on July 5, 2026, a brief but technically ...

As space traffic increases and our reliance on satellites grows, the question of how to manage and predict anomalies in orbital astrodynamics becomes ever more critical. The idea that artificial ...

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 ...

Mystery solved Changes in the Earth's orbit, not human activity, may be behind a subtle increase in methane levels 5000 years ago, according to new research. Over the last four glacial cycles (420,000 ...
