Astronomers have found evidence of the first moon to exist beyond our solar system.

The gargantuan 'exomoon' is similar in size to the gas giant Neptune and orbits a planet 8,000 light years away called Kepler-1625b.

More than 3,000 exoplanets - worlds orbiting stars other than the sun - have been found so far but no 'exomoons' have ever been confirmed.

A Neptune sized moon! Kepler-1625b is about the size of Jupiter but ten times more massive the Jupiter. I would guess the Neptune size object was initially a planet but got captured by Kepler's immense gravity.

That's a pretty far distance for a moon's orbit.....

Wake me up when they discover an exocomet.

Would Kepler 1625bb possibly have subsatellites orbiting it?

Moons are important to the development of life because all planets wobble (like a Billy Kilmer pass) as they spin on their axis. It’s called “nutation,” and all bullets do the same thing.

Anyway, excessive nutation causes the atmosphere to have violent shifts in atmospheric pressure, which means high surface winds, like Saturn. The interplay of gravity between Earth and its moon — which is unusually large compared to its host planet — dampens earth’s nutation and makes our atmosphere calmer and more conducive to supporting life in the doing.

A large moon is one of about a hundred incidental, unusual and unlikely conditions that happened on earth to make it hospitable to emerging life. The theory that that assortment of conditions (including a relatively large moon) probably would be unlikely to occur elsewhere is the basis of the Rare Earth Hypothesis.

Finding exoplanets that have moons in theory improves the possibility that those planets might support life.

Thanks fieldmarshaldj. And thanks for the similar link in FReepmail, FReeper who shall remain nameless.
