The solar system was literally turning ... The key to testing the Nice model is mapmaking. Charting the composition and orbits of distant objects should reveal whether and how the planets cast ...

For a few evenings around 28 February, every planet in the solar system will be visible in the night sky, thanks to a rare great planetary alignment. Here's how to make sure you don't miss this ...

Astronomers have sent artificial satellites (satellites that are manmade) to orbit several Solar System objects, including Jupiter, the asteroid Vesta and Mars. Polar orbits take the satellites ...

The two exoplanets, or planets outside of our solar system, orbit a star called TOI-1453, which is slightly cooler and ...

As a result, thousands of smaller celestial bodies in the outer solar system ... elongated orbits. Until now, there was no explanation for this phenomenon. "The beauty of this model lies in ...

They can perturb orbits and give a little ... pull of the sun," said Gregg. "For this model, we assumed Alpha Centauri acts similarly to our solar system. We simulated various ejection velocity ...

The Sun is the largest object in the Solar System. The Sun’s huge gravitational ... for example, Mercury orbits once every 88 Earth days, but Neptune orbits once every 165 Earth years For ...

Earth has a nearly circular orbit, but some planets outside our solar system, called exoplanets, have very elliptical orbits. UCLA astrophysicists have now measured the shape of the orbits of ...

Scientists from UNSW Sydney have located a potential new exoplanet – a planet that orbits a star outside of our solar system – using ... ran a series of model simulations that pointed to ...

providing fresh insight into planetary evolution beyond our solar system. A new study by Rice University researchers Sho Shibata and Andre Izidoro presents a compelling new model for the formation ...
