Studying the orbits of thousands of exoplanets shows that large planets tend to have elliptical orbits, while smaller planets tend to have more circular orbits. This split coincides with several other ...

Scientists have used data from NASA's retired planet-hunting space telescope 'Kepler' to discover that small and large worlds have very different upbringings. The team found that larger planets on non ...

The star system V1298 Tau reveals that many planets begin as large, low-density worlds that slowly shrink and shed their ...

Astronomers have confirmed a Saturn-size world drifting alone in deep space roughly 10,000 light-years from Earth, a discovery that turns a once-theoretical idea into a measured reality. The planet ...

Planet formation used to sound straightforward: dust clumps into rocks, rocks grow into worlds, and the rest is detail. A ...

Scientists measured mass and distance of free floating planet drifting through space without star for first time.

Astronomers have revealed new evidence that there are not just one but four tiny planets circling around Barnard's Star, the second-nearest star system to Earth. Astronomers have revealed new evidence ...

This illustration shows an exoplanet orbiting around two brown dwarfs –– objects bigger than gas-giant planets but too small to be proper stars. ESO/M. Kornmesser Astronomers have discovered a ...

Astronomers are just beginning to scratch the surface of the complex, and sometimes violent, relationships between planets and their parent stars. When you purchase through links on our site, we may ...
