Here’s a nice and happy face from Planet Mars that is said to be a crater about 3 kilometers in diameter.
This picture of a crater resembling a “happy face” was acquired by the Context Camera (CTX) on Mars Reconnaissance Orbiter on January 28, 2008. The unnamed crater is about 3 kilometers (1.9 miles) across. It is located among the Nereidum Montes, north of the Argyre basin, near 45.1°S, 55.0°W. North is toward the right and sunlight illuminates the scene from the upper right.
