Yeah.

The idea now is that it was shoved into this unusual orbit by another moon called Triton at an earlier point.

Triton is big.

It's about eight times bigger than Nereid.

And it turned out it's kind of a bully.

Yeah, exactly.

Our moon is lucky.

It doesn't have to compete for real estate around Earth.

I talked to Matthew Belyakov from the California Institute of Technology.

He's the lead researcher on a new paper out about this in the journal Science Advances.

Well, this may be the only intact moon remaining from Neptune's original moons.

Matthew says information like this leads to filling in other blanks around the solar system.

Yeah, it all comes back to the James Webb.

Talking to Matthew, he just underscored how much of a game changer this telescope has been.

It's such a powerful tool.

He says in his line of work, it's really like before the James Webb Space Telescope and after the telescope.

It's given us such a richer and more nuanced understanding of the universe.

Five out of five stars.

I'm game to nerd out any time on Space Stuff, guys.

I'm ready.
