Triton Geyser Height
CRYOVULCANIC PLUME MONITOR
Nitrogen Eruption
Triton's geysers shoot plumes of nitrogen gas mixed with dark dust into the thin atmosphere, reaching incredible heights before being carried away by high-altitude winds.
Vertical reach into the exosphere.
Surface temperature during eruption.
Geyser Height
Cryovolcanic Plumes. In Triton's weak gravity, pressurized nitrogen gas erupts through the ice, towering 8 kilometers above the frozen surface.
- π Vertical: 8,000 meters high.
- βοΈ Horizontal: 150 km wind streaks.
- βοΈ Driver: Subsurface Solar Greenhouse effect.
Vertical Limit
8 Kilometers High. In Triton's near-vacuum and weak gravity, nitrogen plumes reach altitudes that dwarf Earth's highest mountains.
- π Vertical: 8 km straight-up ascent.
- π¬οΈ Horizontal: Drifts into 150 km streaks.
- π Gravity: Only 0.779 m/sΒ² (8% of Earth).
Atmospheric Streaks
Horizontal Migration. High-altitude winds catch the dark geyser dust, dragging it across the icy plains to create 150km-long signatures of Tritonβs climate.
- π Range: Over 150 km from the source vent.
- πͺοΈ Velocity: 30β50 m/s high-altitude winds.
- π Material: Dark carbon-rich "tholin" dust.
Sub-Surface Pressure
The Greenhouse Explosion. Trapped solar heat sublimates nitrogen ice into high-pressure gas, turning Triton's crust into a ticking geological time bomb.
- βοΈ Input: Solar penetration through nitrogen ice.
- π¨ Process: Solid-to-gas sublimation.
- β‘ Result: Pressure-driven supersonic eruption.

VERTICAL HEIGHT
Eruptions shoot nitrogen gas and dust plumes directly upward to an altitude of **8 kilometers** (5 miles).
NASA MISSION DATAHORIZONTAL DRIFT
Once the plumes reach the thin atmosphere, they drift horizontally for over **150 kilometers** due to high-altitude winds.

Subsurface nitrogen is heated by the Sun through a "greenhouse effect" in the ice, creating pressure that vents through cracks.
