The distance between two binary or twin stars is same at which Earth orbits the sun. While comparing with sun and planet host star, sun is not much dimmer. Earth (little colder) is not much colder than planet. Four international research team, Andrew Gould (Professor in the Ohio State University in Columbus), on July 4 their published the issue of the journal science.

Scott Gaudi (Professor of astronomy at Ohio State) said "This greatly expands the potential locations to discover habitable planets in future". OGLE-2013-BLG-0341LBb is a planet named by astronomers; it is called gravitational microlensing, by using this method "A planet is also present around the foreground star". With the help of telescope, it can easily study about OZLE (Optical Gravitational Lensing Experiment), MOA (Microlensing Observations in Astrophysics).
