Astrophytum asterias is a small, spineless cactus with a distinctive disc-shaped body that grows 2.5–6 cm (1–2 in) tall and 5–15 cm (2–6 in) in diameter. Its greenish-brown surface is covered in white trichomes (scales), giving it a speckled appearance, and it features 7–10 ribs with woolly areoles. The plant produces vibrant yellow flowers with red bases and woolly outer parts, followed by green to pink oval fruits. Its squat, star-like shape and lack of spines make it visually distinct from many other cacti.
