Astronomers have achieved a first in exoplanet hunting by using the Hubble Space Telescope images to investigate a mysterious ...

Finding another planet at the fringes of the solar system, especially one which came from another star, would be a massive astronomical discovery if confirmed. Let’s just hope any rogue planets ...

Scientists have used gravitational lensing to detect a so-called ‘rogue planet’ that doesn’t orbit a star and floats freely in space. The planet is relatively … ...

"A rogue planet could perturb the orbits of the planets that may be possible to detect," they conclude. We're still in the early days of understanding ISOs and rogue planets.

Astronomers found up to 170 so-called rogue exoplanets by looking for young, hot worlds untethered to any stars.

Conspiracy theorists are claiming that a rogue planet will disrupt Earth’s orbit this Sunday and bring about a series of catastrophic earthquakes that could decimate life as we know it.

Astronomers have found what is likely to be a rogue planet that is around 100 light years from our solar system, making it the closest free-floating planetary mass yet discovered.

A newly published study suggests there could be more "rogue" planets, those that do not orbit a star, than there are stars in the Milky Way galaxy.

Somewhere out there in the midst of the Milky Way is an Earth-sized planet, floating aimlessly through space. The “rogue planet” belongs to no solar system, nor does it orbit a star, like the ...

Could something bigger—an entire rogue planet—catch us by surprise as that asteroid did? The answer to this unnerving question depends on how common rogue planets are.

Planet Nine may be even more exotic than astronomers had thought. The putative world, which some scientists think lurks unseen far beyond Pluto’s orbit, could be a former “rogue planet” that ...
