Facts about Triton's Cryovolcanoes
- 08
Triton's cryovolcanic plumes contain methane and carbon monoxide alongside nitrogen, creating compositionally complex eruptions unlike any other known cryovolcanic system.
- 07
Triton's cryovolcanic terrain covers approximately 40 percent of the moon's surface, making it one of the most geologically active bodies in the outer solar system.
- 06
Triton's cryovolcanic vents expel material at velocities exceeding 1 kilometer per second, comparable to supersonic jets on Earth despite the moon's extremely low surface gravity.
- 05
Nitrogen ice sublimation powers Triton's cryovolcanes, as seasonal heating of subsurface nitrogen deposits creates pressure sufficient to erupt through the moon's icy crust.
- 04
Triton's cryovolcanic activity likely sustains a subsurface ocean beneath its frozen crust, driven by tidal heating from Neptune's gravitational pull.
- 03
Cryovolcanic plumes on Triton reach temperatures around minus 235 degrees Celsius, making them among the coldest eruptions in the solar system.
- 02
Triton's cryovolcanic eruptions deposit dark organic material called tholins across its icy surface, creating the moon's distinctive dark streaks visible in Voyager 2 imagery.
- 01
In 1989, Voyager 2 observed nitrogen geysers erupting up to 8 kilometers high from Triton's cryovolcanoes near the south polar region.
