HD 164595 b is a confirmed exoplanet orbiting around the Sun-like star HD 164595 every 40 days some 94.36 light-years away. It has a mass of 16 Earth masses, most likely due to its high mass it could be a Mini-Neptune, however depending on the planet's density it could be a Mega-World that could be like a terrestrial planet or it could be made out of volatile compressed into a solid form.^[2][3][4]
