Mare Tranquillitatis, Sea of Tranquility
Location: Between Mare Serenitatis and Mare Fecunditatis.
Size: 870 km
Features: Its borders are not clear; it is surrounded by some smaller mountain groups as well as small maria called bays. Best known for being the landing site of the first manned landing, Apollo 11.
Oceanus Procellarum, Ocean of Storms

Size: 86km diameter, 4.8km depth
Features: 100 million years old so young for a lunar crater. Best seen at full moon where rays of ejecta can be seen emanating from it.
Size: 86km diameter, 4.8km depth,
