Consequently, even though it is one of the closest stars to Earth, such that its light takes only six years to get here, it ...

Planet demographics reveal a puzzling lack of worlds in a certain size range throughout the galaxy F or centuries our solar ...

Gaia, a mission designed to map stars, has accidentally become a planet hunter. Using precise astrometry, it detected stellar ...

The Sun has a crazy idea: what if the planets were ordered by size? The answer? PURE CHAOS! UN official makes bold statement ...

Planets change orbit shape around Neptune’s size. Metal-rich stars help giant planets form. Eccentric orbits suggest chaotic planet formation.

The Webb telescope — a scientific collaboration between NASA, ESA, and the Canadian Space Agency — is designed to peer into ...

How does a planet’s size influence its orbit around its parent star? This is what a recent study published in the Proceedings of the National Academy | Space ...

A new study presents a compelling new model for the formation of super-Earths and mini-Neptunes -- planets that are 1 to 4 times the size of Earth and among the most common in our galaxy. Using ...

Astronomers have discovered an Earth-size planet that is showered with so much radiation, its atmosphere eroded away long ago ...

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 ...

Asteroids are rocky objects that orbit the Sun, just like planets do. There are millions of asteroids of very different shapes and sizes. Some are almost spheres, like planets, but most are ...

In 1992 astronomers reported the first planet-size masses around a dead star, the pulsar PSR1257+12, which sits 2,000 light-years away. Three years later came news of the first known exoplanet ...
