Description
More examples of my astronomical art can be seen in my DA "Paleo & Sci Illo" gallery:[link]
Welcome to Tar World.
This is a terrestrial sized planet that is somewhat larger in diameter than Earth. It is however not as dense or as massive.
This planet orbits a pair of main sequence red dwarf stars. These are old very long-lized stars. This binary system was a product of an early phase of star formation in the Milky Way galaxy. As a result, this system is relatively poor in heavier elements. Indeed, this planet lacks an iron core entirely. It may have a small sulfurous core. The rest of the planet's mass is made of hydorcarbon compounds.
This world has no solid surface. It is a constantly convexing mass of tarry goo thousands kilometers deep. The atmosphere is a primordial blend of sulfuric acid and methane.There is a chance of extremophile microbial life, but it is not a pleasant place to dwell.

One might envision rafts of hardened tar at the poles, but there would be no land such as the silicate rock of Earth.

Wouldn't there be hardened tar rafts just floating freely everywhere then, due to the warm, connecting tar, or currents of tar?

It would all depend on the temperature gradient at different latitudes. The equivalent of seasonal tar "icebergs" might be possible.
