Did you know: Saturn's moon Titan has rivers, but they are not made of water ?

Saturn's moon Titan has rivers, but they are not made of water like on Earth. Instead, Titan's rivers are composed of liquid hydrocarbons, primarily methane and ethane. These liquids flow across Titan's surface, carving channels and filling lakes and seas, creating a hydrological cycle similar to Earth's, but with different materials.

Here's a more detailed look:
Hydrocarbon Rivers:
Titan's rivers are made of liquid methane and ethane, which are naturally occurring gases on Earth but remain liquid at Titan's extremely cold temperatures.
Earth-like Features:
Despite the different composition, Titan's rivers have features similar to those on Earth, including canyons, rapids, and even evidence of potential waterfalls.
Hydrological Cycle:
Titan has a complete hydrological cycle, with clouds, rain, rivers, lakes, and seas, all composed of hydrocarbons.
Evidence from Missions:
NASA's Cassini spacecraft provided detailed images and data, revealing these hydrocarbon rivers and other features on Titan's surface.
Missing Deltas:
One intriguing aspect is that while Titan has rivers, it seems to have fewer deltas where rivers meet seas compared to Earth, which is an area of ongoing research.
