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 ...
Titan has a surface gravity of 0.138 g, slightly less than the Moon. Managing long-term effects of low gravity on human health [8] would therefore be a significant issue for long-term occupation of Titan, more so than on Mars. These effects are still an active field of study.
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 ...
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 ...
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.
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 ...
Mimas is the seventh-largest moon of Saturn, which all told has well over 100 moons ranging from Titan - larger than the planet Mercury - to some only the size of a city block.
