Triton Trivia Questions

Triton is about 2,700 km in diameter, slightly larger than Pluto (2,377 km), and both are icy bodies with rock cores, likely originating from the Kuiper Belt.

Voyager 2 spotted dark streaks from cryovolcanic geysers shooting nitrogen and dust, powered by seasonal solar heating.

Triton's retrograde orbit is slowly decaying. In about 3.6 billion years, it will cross Neptune's Roche limit and break apart, creating a spectacular ring.

Triton has a retrograde orbit, meaning it moves opposite to Neptune's spin, a rare trait suggesting it was a captured Kuiper Belt object.

Several large moons have atmospheres, like Titan (thick), Io (thin), and even our Moon has an exosphere. Triton's is thin but not unique.

Triton has no detectable global magnetic field. Its small size and icy composition likely mean it lacks a molten iron core needed for a dynamo.

Triton has relatively few craters; its surface is young and reshaped by cryovolcanism and tectonic activity, erasing most impact scars.

While extremely cold (about -235°C), Pluto and some Kuiper Belt objects can be colder. Triton is one of the coldest, but not the absolute coldest.
