stronomers using NASA's Hubble Space Telescope have photographed one of the smallest objects ever seen

The brain of a Democrat?

it's also large enough to be a brown dwarf, a failed star

Shown here gravitationally bound to its companion star...

Last I heard, a brown dwarf was 13-80X the mass of Jupiter.

So, fresh from their victory over the now re-defined dwarf planet Pluto, they now want to create
a new class, Dwarf Brown Dwarf?

I'm sure it is quite important to someone, astronomers or astrologists or semanticists.

Personally, I subscribe to the "if it walks like a duck" school:

It circles a sun,
It has an established orbit around that sun,
It's bigger than a bread basket,
It isn't giving off huge amounts of solar radiation...

Sounds like a planet to me.

Wouldn't a brown dwarf be a gas giant? As long as it doesn't have fusion from its mass, wouldn't it still be a planet?

Alien planet poised to reveal all its secrets

Luhman argues that any future definition of the term that includes extrasolar planets should stipulate that the objects form from a disc of gas and dust around their host star – and not from a collapsing gas cloud.

This find would be excluded from planetary status if such a definition were adopted, a situation that Luhman says is interesting in itself. "It's a neat idea that you have a planetary-mass companion that may not really be a planet," he says.
