Their study also suggests that in addition to asteroids and comets, the sun could capture rogue planets throughout eons.

This is important context for understanding both star and planet formation.” What are rogue worlds? Also called rogue planets, these free-floating celestial objects have masses similar to planets.

The Nancy Grace Roman Space Telescope will expand the search for exoplanets as well as rogue planets, or worlds that travel through space without orbiting stars.

NASA's exoplanet hunter TESS may have detected its first free-floating planet with a little help from Einstein.
