Planets are bodies that orbit a star and have sufficient gravitational mass that they form themselves into roughly spherical shapes that, in turn, exert gravitational force on smaller objects around ...

Somewhere beyond Neptune, the Kuiper Belt is bent. Not by much, and not in a way any known planet can account for. A study published in Monthly Notices of the Royal Astronomical Society: Letters in ...

Astronomers discovered exoplanet WD 1856 b closely orbiting a white dwarf, offering insights into planetary survival after a star's violent demise.

Add Yahoo as a preferred source to see more of our stories on Google. University of North Carolina researchers have recently discovered a baby exoplanet that could challenge our current understanding ...

Within their planetary systems, stars are continuously shaping their orbiting planets through gravity, radiation and magnetic forces. So far, this relationship has appeared to be a one-way street.

A Jupiter-size exoplanet orbiting a dead star baffled astronomers. But the planet named WD 1856 b could preview the fate of ...

Astronomers have made the first measurement of spin-orbit alignment for a distant ‘super-Jupiter’ planet, demonstrating a technique that could enable breakthroughs in the quest to understand how ...

Two teams of astronomers have found that extrasolar planet HAT-P-7b, discovered in 2008, has a retrograde or highly tilted orbit. On UT May 30, 2009, a Japanese collaboration team led by Norio Narita ...

GJ 3378b has moved closer to the kind of world astronomers most want to find: small, rocky, temperate, and near enough for future telescopes to inspect in far greater detail. The planet circles a red ...
