Nowhere to Hide: Elusive Small Rogue Planet Candidate Detected in the Depths of Space


Since planets such as the one that was discovered do not orbit any host star, scientists had to employ some not-so-traditional methods to spot it.

A team of astronomers from Poland has announced the discovery of the smallest of the Earth-sized “rogue planets”, ie planets that do not orbit a star directly, to date, SciTechDaily reports.

According to the media outlet, such free-floating planets cannot be detected via traditional methods since they do not orbit a host star, but researchers from the Optical Gravitational Lensing Experiment (OGLE) project managed to achieve this feat by employing microlensing.

The discovery of the “shortest-timescale microlensing event ever found”, designated OGLE-2016-BLG-1928 and which has the timescale of 42 minutes, was reported by scientists on 29 October.
