Neptune's Moons Are Caught in One of The Strangest Orbits Ever Seen

“If you were stationed on Thalassa, you’d see Naiad passing above and below in a pattern that would repeat itself every four loops, as Naiad repeatedly laps its neighbour.”

It’s almost like one moon orbits the other. A moon’s moon.

Trump’s fault....

That’s actually pretty cool.

We are about to send our fifth? rover to Mars in a few weeks....why not to a moon of Mars or a moon of a outer planet instead?
I understand keeping the NASA budget perpetually funded and all but still..

...or a moon of a outer planet

Done did. 2005...............

Ah-Ha!

It’s the old, ‘Boy meets Girl, Boy Loses Girl, Boy Wins Girl Back’ orbit! ;)

[BipolarBob]

Lunar entanglement.

[NTHockey]

Looks like a sine wave. Alternating current?

Thanks Red Badger.

Naiad takes seven hours to make one revolution around Neptune. Phobos takes seven hours to make one revolution around Mars.

Coincidence? Or Russian collusion?

[SunkenCiv]

These Saturnian moons should have been brought up in that “counter-Earth” topic, ah well:

According to the picture, it appears that Naiad always has a slightly shorter radius orbit than Thalassa so they never collide. Just coincidence? Doubting that.

[Night Hides Not]

Let's just be thankful it's not Uranus.

Sorry...

[EvilCapitalist]

Don’t be sorry. We need a good laugh.

There is growing interest in returning to Neptune and Uranus (please...behave). This article does a nice job of laying out the pros and cons, chiefly The problem with outer solar system exploration is, you want a spacecraft moving fast enough to reach its intended destination in a decade or so — but too much speed makes slowing down to enter orbit out of the question

I don't believe Congress was granted an enumerated power in the Constitution to create NASA - it's not serving a military function, and the power of pursue pure exploration isn't an Article 1, Section 8 power.

That's said, I love space exploration and think mankind got a lot out of Veejer and New Horizons etc. I want to return to Neptune and Uranus (again..behave children).
