Step 1 : Introduction to the question "Which planet is orbited by two small moons named Phobos and Deimos?"
...Mars, often called the Red Planet, has two tiny, irregularly shaped moons named Phobos and Deimos. Discovered in 1877 by American astronomer Asaph Hall, they are believed to be captured asteroids from the nearby asteroid belt. Phobos, the larger of the two, orbits so close to Mars that it appears to move across the sky in just a few hours and is slowly spiraling inward, destined to break apart or crash into the planet in tens of millions of years. Deimos, smaller and farther out, has a smoother surface and a more leisurely orbit.
