Rogue Planets: Not as Plentiful as Thought

A new study finds that rogue planets those floating free in the galaxy, unbound to any star are not as plentiful as we once thought.

Astronomers know that there are rogue, Jupiter-sized planets roaming the galaxy on their own, without a star to call home. But how many dark and lonely planets are out there?

Six years ago, a study found that they might be so abundant, they outnumbered the stars two to one. The result had implications not only for how these dark planets might form, but also for the general messiness of the early years of planet formation. Now, a new study using the exact same technique has contradicted that first result turns out there aren't nearly as many of these dark, Jupiter-sized worlds as we once thought.
