Titan (Moon of Saturn)

Recent scientific finding: Re-analysis of data from NASA’s Cassini spacecraft suggests that Titan may not possess a subsurface ocean, contrary to earlier scientific assumptions.
Planetary status: Titan is the largest moon of Saturn and the second largest moon in the solar system, after Ganymede.
Discovery: It was discovered by Dutch astronomer Christiaan Huygens.
Size: Titan has a radius of about 2,575 km, making it larger than Earth’s Moon.
Atmosphere: It is the only moon with a dense atmosphere, composed mainly of nitrogen, with methane present.
Surface features: Titan is the only celestial body besides Earth known to have rivers, lakes, and seas of liquid on its surface.
Methane cycle: It exhibits an Earth-like methane cycle, involving rainfall, surface flow, and evaporation, though methane replaces water.
