The atmosphere of Titan is the dense layer of gases surrounding Titan, the largest moon of Saturn.Titan is the only natural satellite of a planet in the Solar System with an atmosphere that is denser than the atmosphere of Earth and is one of two moons with an atmosphere significant enough to drive weather (the other being the atmosphere of Triton).

Before the arrival of Voyager 1 in 1980, Titan was thought to be slightly larger than Ganymede, [18] which has a diameter 5,262 km (3,270 mi), and thus the largest moon in the Solar System. [ 37 ] [ 38 ] [ 39 ] This was an overestimation caused by Titan's dense, opaque atmosphere, with a haze layer 100–200 km above its surface.
The average surface temperature is about 90.6 K (-182.55 °C, or -296.59 °F). [2] At this temperature water ice has an extremely low vapor pressure, so the atmosphere is nearly free of water vapor. However the methane in the atmosphere causes a substantial greenhouse effect which keeps the surface of Titan at a much higher temperature than ...
Titan, 3,200 miles (5,150 km) wide, is our solar system's second-biggest moon behind Jupiter's Ganymede and is larger than the planet Mercury. Titan and Earth are the only worlds in the solar ...
Parts-per-million chart of the relative mass distribution of the Solar System, each cubelet denoting 2 × 10 24 kg. This article includes a list of the most massive known objects of the Solar System and partial lists of smaller objects by observed mean radius. These lists can be sorted according to an object's radius and mass and, for the most ...
Ganymede and Titan are additionally larger than the planet Mercury, and Callisto is almost as large. All of these moons are ellipsoidal. That said, the two moons larger than Mercury have less than half its mass, and it is mass, along with composition and internal temperature, that determine whether a body is plastic enough to be in hydrostatic ...
Mimas, not precisely round, has an average diameter of about 250 miles (400 km). It is tidally locked, meaning it perpetually shows the same side toward Saturn, as our moon does toward Earth.
Astronomers believe the mysterious “magic islands” on Saturn’s moon Titan are honeycomb-like frozen clumps of organic material that fall like snow on the moon.
