Mare Serenitatis

Description: Mare Serenitatis, the Sea of Serenity, is a large circular mare on the Moon's near side, measuring 707 kilometers in diameter, formed by lava filling an ancient impact basin. Its dark basaltic plain is bordered by the Taurus Mountains and features wrinkle ridges and rilles, indicating tectonic activity. The region has a high titanium content in its lava, making it bluer than other maria.

How I Got My Name: "Mare Serenitatis" is Latin for "Sea of Serenity," named by early astronomers based on folklore associating lunar phases with calm weather.

Interesting Fact: Borders the Taurus Mountains; visited by Apollo 17 nearby in 1972. The mission discovered layered deposits and volcanic beads, dating the lava to 3.7 billion years, contributing to understanding the Moon's volcanic phases and mantle composition.

Location: Centered at 28.0° N, 17.5° E, 707 km diameter.
