How fast can rogue planets grow? This is what a recent study published in The Astrophysical Journal Letters hopes to address as a team of scientists invest | Space ...

Rogue planet Cha 1107-7626 is swallowing gas and dust at roughly six billion tons each second, the fastest planetary growth ever recorded.

A runaway “rogue planet” is gorging on space dust at a rate of six billion tonnes per second. The event marks the fastest planetary growth ever observed, hinting that some planets form more like stars ...

About 620 light-years from Earth, a gigantic rogue proto-planet is currently devouring 6.6 billion tons of dust and gas per second. Based on recent observations, the relatively new resident of the ...

Rogue planets live by their own rules, freely floating through the cosmos without being bound to a star. With no stellar supervision, those isolated planetary bodies can often behave in unusual ways.
