1RXS J160929.1-210524 is a Pre-main sequence star in constellation scorpius. " Most of the potential exoplanets imaged to date have been seen orbiting brown dwarfs, which are dim - making it easier to detect companion objects. " §
Planet
1RXS J160929 b is Jupiter hot planet. " Canadian Astronomers at the University of Toronto believe that the point of light that can be seen above and left of the star 1RXS J160929.1-210524, 500 light-years from Earth, may be a planet. The star is similar to the mass of the sun.
