This artist’s impression shows an example of a rogue planet detected in the Rho Ophiuchi region where ESO observations have recently helped uncover at least 70 of these objects.
Rogue planets have masses comparable to those of the planets in our Sola A team of researchers has uncovered nearly 70 rogue planets in our galaxy, the largest group ever discovered, according to the European Southern Observatory.
Rogue planets are described as "elusive cosmic objects that have masses comparable to those of the planets in our Solar System but do not orbit a star, instead roaming freely on their own," according to a press release.
