Titan is the only object in the outer Solar System where a spacecraft has landed and conducted surface operations. The geology of Titan encompasses the geological characteristics of Titan, the largest moon of Saturn. Titan's density of 1.881 g/cm 3 indicates that it is roughly 40–60% rock by mass, with the rest being water ice and other ...
For example, Titan looks bigger than Ganymede, but its solid body is smaller. For the giant planets , the "radius" is defined as the distance from the center at which the atmosphere reaches 1 bar of atmospheric pressure.
Frequently described as a planet-like moon, Titan is 50% larger in diameter than Earth's Moon and 80% more massive. It is the second-largest moon in the Solar System after Jupiter's Ganymede and is larger than Mercury; yet Titan is only 40% as massive as Mercury, because Mercury is mainly iron and rock while much of Titan is ice, which is less ...
All of the rocky inner planets, as well as the moon, have an iron-dominant core. Venus and Mars have an additional major element in the core. Venus’ core is believed to be iron-nickel, similarly to Earth. Mars, on the other hand, is believed to have an iron-sulfur core and is separated into an outer liquid layer around an inner solid core.

It turns out that the moon of Saturn has certain advantages for future space colonists not present on the moon or Mars. Opinion - The NASA-SpaceX launch to Titan sparks dreams of colonization Skip ...
It is slightly more massive than the second most massive moon, Saturn's satellite Titan, and is more than twice as massive as the Earth's Moon. It is larger than the planet Mercury, which has a diameter of 4,880 kilometres (3,030 mi) but is only 45 percent of Mercury's mass. Ganymede is the ninth-largest object in the solar system, but the ...
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.
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 ...
