Study finds Neptune's moon Nereid may be original survivor of ancient collision

A new analysis using James Webb Space Telescope data suggests that Nereid, Neptune's third-largest moon, is the sole intact survivor from an original set of moons destroyed early in the solar system's history. The findings support the hypothesis that Triton, Neptune's largest moon, was captured from the Kuiper Belt billions of years ago and collided with Neptune's primordial satellite system, scattering or destroying the original moons.
