On Earth the condensing substance is typically water vapor, which forms small droplets or ice crystals, typically 0.01 mm in diameter. When surrounded by billions of other droplets or crystals they become visible as clouds.

The average centre-to-centre distance from the Earth to the Moon is 384,403 kilometres (238,857 mi), about thirty times the diameter of the Earth. The Moon's diameter is 3,474 kilometres (2,159 mi),[4] a little more than a quarter of that of the Earth. The pull of gravity at its surface is about 17 percent of that at the Earth's surface. The Moon is the only celestial body on which human beings have made a manned landing. (Jupiter and it's bands of clouds can be seen at the end.)
