Astronomers have detected an Earth-size planet candidate orbiting a nearby star once a year, making it a promising target for ...

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, ...

Astronomers studying a faint red dwarf star called LHS 1903 have found a four-planet system arranged in a sequence that no standard model of planet formation predicted. The system follows a ...

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 ...

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 ...

A slew of recent studies have used computer simulations to model the hypothetical conditions on rocky exoplanets with exotic orbits and spin states. What they show is that, contrary to the standard ...

Astronomers have uncovered a distant planetary system that flips a long-standing rule of planet formation on its head. Around the small red dwarf star LHS 1903, scientists expected to find rocky ...
