The Moon That Survived Neptune's Apocalypse

Añadido: 2026-06-08

[00:00:00]4 billion years ago, Neptune may have lost almost all of its moons.

[00:00:04]Scientists think Neptune once had an entirely different moon system.

[00:00:09]Then Triton arrived.

[00:00:11]A giant moon that wasn't born there.

[00:00:14]When Neptune captured Triton, its gravity may have thrown the entire system into chaos.

[00:00:19]Some moons may have crashed into each other.

[00:00:22]Others may have been ejected into space forever.

[00:00:26]But one moon appears to have survived.

[00:00:27][music] Its name is Nereid.

[00:00:31]Nereid follows one of the strangest orbits in the solar system.

[00:00:35]Sometimes it travels much farther from Neptune than scientists [music] would normally expect.

[00:00:41]New research suggests that unusual orbit may be evidence of something extraordinary.

[00:00:46]Nereid may have lived through the destruction of Neptune's original moon family.

[00:00:51]Most ancient disasters leave behind scars.

[00:00:54]This one may have left behind a witness.

[00:00:57]A moon called Nereid.
