A new study by Rice University researchers Sho Shibata and Andre Izidoro presents a compelling new model for the formation of ...

The shape of a planet's orbit is one of its fundamental properties, along with its size and distance from its host star.

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

Our solar system's journey around the center of the Milky Way takes it through varying galactic environments, and one may ...

Diminutive Barnards Star is closer in size to Jupiter than to the Sun. Only the three stars that make up the Alpha Centauri ...

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

Astronomers have identified a quartet of small rocky planets orbiting Barnard's star - one of our closest stellar neighbors - ...

Astronomers have revealed new evidence that there are not just one but four tiny planets circling around Barnard's Star, the second-nearest star system to Earth.

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

Not that it was a competition, but Saturn surpassed Jupiter in known moons a few years ago. Now the giant planet may never ...

Barnard's Star is a small, dim star, of the type that astronomers call red dwarfs. Consequently, even though it is one of the ...
