That's no moon.
-
Unlike moons in our Solar System, this object — a gaseous body at least as massive as Jupiter — does not orbit a planet.
It circles a brown dwarf, that in turn orbits the CD-35 2722 star.
Regardless of what to call this object, this discovery may mark an important first.

@esoastronomy The definition of moon feels like a wave function.

That's no moon. It's a...hang on, what should we call it?
Our VLT has revealed evidence for a moon-like object in the CD-35 2722 system. Yet this new ‘exomoon’ detection is challenging cosmic labels!

@esoastronomy You nailed it. Death Star it is!

@amoroso @esoastronomy . It’s a planet circling a dying star that happens to be getting pulled into another star. this feels more like a captured solar system degrading into its neighbor than a moon to me.

@passwordsarehard4 Agreed.

@passwordsarehard4 @amoroso Note that the intermediate object is not a dying star, it's a young brown dwarf – an object that never became a star. It's more massive than a planet but not massive enough to sustain nuclear fusion in a prolonged way.

@passwordsarehard4 @amoroso @esoastronomy If it's pulled into another star, what's the state of that star? Sounds like a black hole or what happens when they collide?

I wonder if this „moon“ has its own moons… -
