Deimos

One of the two moons of the planet Mars. It is irregularly shaped, 15 × 12 × 11 km/9 × 7.5 × 7 mi, orbits at a height of 24,000 km/15,000 mi every 1.26 days, and is not as heavily cratered as Mars's other moon, Phobos. Deimos was discovered in 1877 by US astronomer Asaph Hall, and is thought to be an asteroid captured by Mars's gravity.

NASA's Viking 2 probe visited Deimos in 1977, flying within 29 km/18 mi of the Moon's surface and taking detailed photographs of its pitted and boulder-strewn landscape.
