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, ...
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 ...
As planetary systems evolve, gravitational interactions between planets can fling some of them into eccentric elliptical orbits around the host star, or even out of the system altogether. Smaller ...
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 ...
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 ...
EVANSTON, Ill. — Except for the fact that we call it home, for centuries astronomers didn’t have any particular reason to believe that our solar system was anything special in the universe. But, ...

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 ...
‘Star Wars’ predicted it: Planet discovered that orbits two suns like Luke Skywalker’s home Tatooine
Is it a two-for-sun deal. Astronomers were blown away after discovering a bizarre exoplanet that orbits twin stars closer than any ever seen before in a binary star system, per a starry study ...
After studying thousands of computer simulations of the solar system, researchers at Rice University and the Planetary Science Institute think there’s a 40% chance an elusive “Planet Nine” or “Planet ...
Theorbits of Jupiter, Saturn, Uranus and Neptune may have been altered by the fly-by of an enormous object from deep space, billions of years ago. According to a pre-print research paper, which is yet ...

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 ...
