This list contains a selection of objects 50 and 99 km in radius (100 km to 199 km in average diameter). The listed objects currently include most objects in the asteroid belt and moons of the giant planets in this size range, but many newly discovered objects in the outer Solar System are missing, such as those included in the following ...
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.
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 ...
The sizes are listed in units of Jupiter radii (R J, 71 492 km).This list is designed to include all planets that are larger than 1.6 times the size of Jupiter.Some well-known planets that are smaller than 1.6 R J (17.93 R 🜨 or 114 387.2 km) have been included for the sake of comparison.
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 ...
On a human time scale, these perturbations can be accounted for using numerical models, [53]: 9-6 but the planetary system can change chaotically over billions of years. [ 54 ] The angular momentum of the Solar System is a measure of the total amount of orbital and rotational momentum possessed by all its moving components. [ 55 ]
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 ...
