A newly discovered object speeding through our solar system is sparking excitement among astronomers because it's not from ...

Estimates of A11pl3Z's orbit are changing fast, but it is clear that it barely bends on its way past the Sun, being very much ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

Finally, the Earth moves a little bit beyond one complete revolution, so the stick again points towards the sun for a second ...

Though the space debris issue has been taken more seriously in recent years, scientists have discovered that destructive ...

How long does it take Pluto to orbit the sun? Learn more about how this planet makes one lap around our Solar System.

The Indian Space Research Organisation (ISRO) is planning a second SpaDeX mission to dock two satellites in an elliptical orbit.

"Our simulations show that these vortex lines are aligned with the total angular momentum and follow circular orbits inside the soliton," Valageas said. "The rotation is not like a smooth wind but ...

Asteroids with ‘unstable orbits’ hide around Venus—do they threaten Earth? New research on the orbits of these mysterious asteroids near Venus stress the need for better space rock surveillance.

Their findings showed that a number of low-eccentricity asteroids—those with nearly circular orbits—could pose a real threat to Earth. Unfortunately, these are also the most difficult to detect.

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Smaller planets, it was revealed, tended to have nearly circular orbits, while larger giant planets have flattened, or elliptical, orbits. This would have been an important finding in isolation ...
