Is there actually a 'planet' composed of "loose quarks"?

Years ago I read in a newspaper about the discovery of a celestial body, spherical which is relatively near our solar system and it is composed entirely of so called “Loose” Quarks… just wondering if this was proven to be true? Apparently if so, this object could have a density greater than our whole solar system combined.

Google is a wonderful tool.

Apparently it’s more complicated than that,

Squishy or Solid? A Neutron Star’s Insides Open to Debate The core of a neutron star is such an extreme environment that physicists can’t agree on what happens inside.

But a new space-based experiment — and a few more colliding neutron stars — should reveal whether neutrons themselves break down. …

Squishy or Hard?
Whatever might be inside the core of a neutron star — loose quarks, or kaon condensates, or hyperons, or just regular old nucleons — the material must be able to hold up to the crushing weight of more than a sun’s worth of gravity. Otherwise, the star would collapse into a black hole. But different materials will compress to different degrees when squeezed by gravity’s vise, determining how heavy the star can be at a given physical size. …
