HD 164595 b is a confirmed exoplanet orbiting around a Sun-like star HD 164595 every 40 days some 94.36 light-years away.
It is believed to be a Neptune-like gassy planet incapable of supporting life. The planet has a mass of 16 Earth masses.
Possible radio signal from star system
A recent (2016) radio signal at 11 GHz (2.7 cm wavelength) has been observed from the HD 164595 stellar system. It is unknown which planet of that stellar system is involved, if any. It could instead be gravitational lensing from a more distant source. SETI investigators are looking into it, but the chances of the signal being from an extra-terrestrial civilization are considered slim, at best.
