Titan may be larger than the planet Mercury--and (the dwarf planet) Pluto-- but it is still considerably smaller than the Earth. Despite Titan's diminutive size, its atmosphere is dense enough that the barometric pressure at Titan's surface is one-and-a-half times greater than that of the Earth's at sea level.
