Glossary term: Triton
Description: Triton is the largest moon of the planet Neptune. It is larger than Pluto, and in fact, because of the unusual properties of its orbit and from what we know of its composition, Triton may well be a dwarf planet captured by Neptune. Triton has an icy surface, with water ice covered by a layer of frozen nitrogen, surrounding a mostly rocky core. Voyager 2, so far the only space probe to visit Triton, discovered that the moon is geologically active, with geysers blowing out nitrogen gas, and very probably with ice volcanoes ("cryovolcanoes") – analogous to Earth's volcanoes, but with water and ammonia instead of liquified rock.Related Terms:
