Star got its name in honor of the project SWEEPS ( Eng. Sagittarius Window Eclipsing Extrasolar Planet Search), in which it was discovered a planetary companion. Planetary System
In 2006 a group of astronomers working in the program SWEEPS, it was announced [1] the discovery of the planet SWEEPS-04 in the system. The planet is a gas giant , is close accesses (at 0.05 a. e ) of the parent star. Therefore, it is referred to the class of hot Jupiters . The discovery was made using the transit method .
