TL;DR: In this paper, a cold terrestrial planet orbiting one member of a binary star system was detected using gravitational microlensing, and the planet has low mass (twice Earth's) and lies projected at ~0.8 astronomical units (AU) from its host star, about the distance between Earth and the Sun.

TL;DR: In this paper, the authors analyzed OGLE-2013-BLG-0102 and found that the event was produced by a binary lens with a mass ratio between the components of q = 0.13 and the anomaly was caused by the passage of the source trajectory over a caustic located away from the barycenter of the binary.
