Over the past decade or so, astronomers have speculated about the characteristics of rogue planets in the Milky Way galaxy. These "free-floating" worlds don't orbit stars, but instead roam the ...

NASA has confirmed that there are over 6,000 exoplanets floating out there in the galaxy, with another 8,000 exoplanets that ...

Planets usually stay close to their host stars, tracing steady paths shaped by gravity. Yet some planets break free and drift alone through the Milky Way.

Astronomers have signalled the discovery of a planetary body roaming the Milky Way that is not gravitationally bound to the Sun or any other star. The entity is termed a free-floating planet, a class ...

Astronomers have just confirmed for the first time the existence of a "rogue planet"—a world drifting in space without being tied to any star.

It's estimated there may be trillions of rogue planets wandering through the Milky Way, unbound to any star. Since detecting our first ones, we have been presented with an odd mystery.

Building on eight years of extraordinary discoveries by the Sloan Digital Sky Survey (SDSS and SDSS-II), a new program of four coordinated surveys will revolutionize the study of the distant universe, ...

Scientists measured mass and distance of free floating planet drifting through space without star for first time.

(CNN) — Scientists may have detected signs of a planet transiting a star outside of the Milky Way, in what could be the first planet ever to be discovered outside our galaxy. The possible exoplanet ...
