HD 164595 b
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.〔(Exoplanets: From Exhilarating to Exasperating )〕〔27:00, "Remember this is a very massive planet which means those same minerals are highly compressed so what you see in the density is mostly due to compression rather than different composition, so the composition comes out to being a combination of rocks and some volatiles five to ten, fifteen percent at most of water", (YouTube )〕
