Is It a Star, or Is It a Planet?

Discovery Narrows the Gap Between Planets and Brown Dwarfs

"The coolest-known star-like object beyond the solar system is giving
astronomers a new look at the differences between massive planets and
the smallest brown dwarfs. This newly discovered object, called ULAS
J0034-00 and located in the constellation Cetus, has a record-setting
surface temperature of 600-700 K, cooler than any known solitary brown
dwarf. In addition, it's a relative lightweight, with an estimated
mass of only 15-30 times that of Jupiter (although they both have
about the same diameter)."

I thought the distinction went like this:

Star - at some stage during its life can initiate and sustain the p-p chain
thermonuclear reaction. (Until it runs out of fuel)

Brown Dwarf - Can at some stage during its' life initiate and sustain
deuterium burning (until it runs out of fuel) but not the p-p chain.

Planet - neither of the above.

Things are not the same for a dwarf planet like Pluto was
changed to 134340 or Eris. Black holes are newly attempted to be called
gravistars even though they don't in main condensed sequence emit
visible stellar light and are nightbat "Black Comets". Planets that emit
or reflect more light then observed in same quadrant but comparative to
distant neighborhood stars are now reclassifiable. Are they all just
particular certain stage exo-cosmic bodies including various stage size,
Moons, asteroids, or comets? What makes a star then a real star, the
observed intrinsic power to self illuminate?

Well then that's easy, a Star like a profound Earth Science Team Officer
is really really bright, glows intensely, comes in various sharp
colorful sizes. It is reliable and directionally vector relative
location pointing, permits theoretical p-p chain fusion of energy to
mass and Super Nova vise versa more complex atomic element conversion.
Beautiful Cosmic Galaxies and Stars fan out as far as we can possibly
detect them. The profound Earth Star Officers on the other hand are very
unique, presently net numbered limited, deep theoretically pondering
brilliant, and extremely rare.
