In Greek mythology, Ganymede is the son of Tros of Dardania, [6] [7] [8] from whose name "Troy" is supposedly derived, either by his wife Callirrhoe, daughter of the river god Scamander, [9] [10] or Acallaris, daughter of Eumedes. [11] Depending on the author, he is the brother of either Ilus, Assaracus, Cleopatra, or Cleomestra. [12]
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 ...

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 ...
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".
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.
