A new study by researchers at the California Institute of Technology (Caltech) suggests that Neptune's moon Nereid could be the sole survivor of a violent 'lunar cataclysm,' explaining its unusual formation.

Scientists propose that Nereid, one of Neptune's moons, could be the only intact remnant of an ancient satellite system, with a new study suggesting it may be an original moon.

A new study suggests that Nereid is Neptune's only original moon, having survived an ancient 'inferno' in the planet's orbit while other original moons were destroyed by objects from the Kuiper Belt.

Scientists are re-evaluating Neptune’s distant moon Nereid, suggesting it might be the last surviving original moon of the planet that endured a cosmic collision.
