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, ...

Why are our planets tilted? Warped disks may reveal the answer
Every planet in the solar system leans, some gently, some dramatically, and that tilt quietly shapes everything from our ...
Planets orbit their parent stars while separated by enormous distances – in our solar system, planets are like grains of sand in a region the size of a football field. The time that planets take to ...
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 ...

Astronomers found a planet with no star, 10,000 light-years away
Astronomers have just confirmed one of the strangest kinds of worlds imaginable, a planet drifting through the galaxy with no ...
A newly discovered exoplanet is rewriting the rules of what planets can be. Orbiting a city-sized neutron star, this ...
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, ...
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 ...
Exoplanet PSR J2322-2650b, orbiting a pulsar, possesses an unprecedented helium-and-carbon-dominated atmosphere, characterized by molecular carbon (C3 and C2) and soot clouds, a composition unlike any ...
‘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 ...
An illustration of the solar system and the planet's orbits around the sun When you're standing on Earth's surface, it's easy to forget that our planet is hurtling around the sun at more than 67,000 ...
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 ...
