asteroide
/asteˈɾoide/ · B2 · adj
asteroid
☄️⭐ aster = star + -oide = like → star-like; space rocks that look like star dots
Greek aster means star, and the suffix -oide means resembling. Asteroids looked like tiny star points through early telescopes, unlike planets, which showed discs. So asteroide literally means star-like or star-shaped.
