Astrophysics

Planetesimal

A primitive early Solar System body shown as a small compact rocky object, gray-brown to dark gray-brown in color, with a rough cratered surface, coarse stony or rubble-like texture, and an uneven irregular shape ranging from potato-shaped to roughly spherical and lumpy. The silhouette is rugged rather than smooth, with shallow craters, crater scars, and occasional scattered boulders; some variants may include small brighter icy patches on the otherwise rocky surface. It appears larger than a meteorite fragment but far smaller than a planet, like an asteroid-like building block of planetary formation. Style: simple scientific clipart, muted earthy palette, soft cel shading, medium detail.
