Circular chalkboard

A generic massive compact halo object depicted as a small compact dark astronomical body, nearly black, charcoal-gray, or dim brownish in color, with little to no emitted light. It appears spherical or disk-like in silhouette with minimal surface detail, possibly slight texture, and is made visible mainly by a faint outline, subtle rim highlight, or weak gravitational-lens-style glow. The object is visually ambiguous between a faint compact remnant and a dim substellar body; simple scientific clipart style with clean edges, minimal detail, soft rim highlight, and muted dark grayscale palette
