Southwest Research Institute scientists propose a new model for the formation of compact exoplanetary systems that contain multiple rocky planets in tight orbits around their star. In this model, ...

Cosmic rule breaker planet discovered that shatters how rocky worlds form
Astronomers studying a dim red dwarf star called LHS 1903 have found a four-planet system with an architecture that defies the standard rules of how rocky worlds take shape. The outermost planet in ...

How to see six planets in the sky at once in rare celestial alignment
Nearly all of the solar system’s planets are about to file across the night sky in a planetary alignment, and it will be ...
Add Yahoo as a preferred source to see more of our stories on Google. An artist's impression of a planetary system with four planets, around a small red star, called LHS1903 with a large reddish-brown ...
The shape of a planet's orbit is one of its fundamental properties, along with its size and distance from its host star. Earth has a nearly circular orbit, but some planets outside our solar system, ...
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 ...
OK, first, let’s get the name out of the way. Scientists have cataloged this exoplanet as PSR J2322-2650 b. It’s called that because it orbits a pulsar (a rapidly rotating neutron star) designated PSR ...
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 ...
