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

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

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 ...

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

The data was gathered from the deepest-ever survey of NGC1333, a star-forming cluster located about 1,000 light-years from Earth. The newly discovered planets are among the lightest ever detected and ...

The finding points toward two distinct pathways for forming small and large planets. The shape of a planet’s orbit is one of its fundamental properties, along with its size and distance from its ...

UCLA astrophysicists have now measured the shape of the orbits of exoplanets—from the size of Jupiter down to the size of Mars—and shown that small planets have nearly circular orbits, while ...
