Mare Imbrium

Mare Imbrium, also known as the Sea of Rains, is one of the largest lunar maria on the Moon's surface. It’s a vast, dark basaltic plain formed billions of years ago when a massive asteroid impact created a basin that was later filled with volcanic lava. This smooth, dark area is visible from Earth and resembles a sea, hence the name. Mare Imbrium plays a key role in lunar geology, offering insights into the Moon’s volcanic history and impact processes. It covers roughly 1.1 million square kilometers, making it a prominent feature in lunar exploration and observation.
