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 ...
Many trans-Neptunian objects (TNOs) have been discovered; in many cases their positions in this list are approximate, as there is frequently a large uncertainty in their estimated diameters due to their distance from Earth. Solar System objects more massive than 10 21 kilograms are known or expected to
The largest lake, Kraken Mare, is larger than the Caspian Sea. [75] Like Europa and Ganymede, it is believed that Titan has a subsurface ocean made of water mixed with ammonia, which can erupt to the surface of the moon and lead to cryovolcanism. [72] On 2 July 2014, NASA reported the ocean inside Titan may be "as salty as the Earth's Dead Sea".
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.
Saturn's moon Mimas is known for its uncanny resemblance to the dreaded Death Star in the original "Star Wars" movie. Astronomers said on Wednesday that data obtained by NASA's Cassini spacecraft ...
It was four times the size of Mount Everest, unleashed a tsunami bigger than any in known human history and boiled the oceans — but an ancient meteor may also have nurtured life on Earth after ...
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 ...
