Sea of Tranquillity（Latin: Mare Tranquillitatis, meaning "Sea of Tranquillity" or "Sea of Tranquillity")MoonIn the Jinghai impact basinMoon Sea。The area is about 420000Square kilometers, 1700 meters below the surface of the moon.

Compared with other parts of the moon, the Sea of Tranquillity presents aLight blue, when extracting and processing colors from multiple photos, the color is very prominent, which is likely to beBasaltThe reason why the metal content of soil or rock is higher.
Unlike many other moonseas, the Jinghai Center does notmass concentration （Mass tumor）Or highfield of gravity。Five American moons in 1968TrackerThe spacecraft's Doppler tracker is located in other lunar sea centers (such asChenghaiorRainy Sea）Mass tumor was found.Later orbiters, such asLunar Prospector Both Grail and Grail have mapped out those gravity fields with high precision, revealing their irregular patterns.

Harmony Bay
Harmony Bay(Sinus Concordiae) is located in the Shaan Narrow Moon Bay at the east end of the Jinghai Sea.To the north is calledSlumberAnd the southern boundary is like ruinsDa VinciA rugged mountain area in the crater, the lunar surface coordinates are 10.8 ° north latitude, 43.2 ° east longitude and 142 km in diameter.[1]
Honor Bay
At the west end of JinghaiHonor Bay(Sinus Honoris), 11.7 ° north latitude and 18.1 ° east longitude on the lunar surface coordinate, with a diameter of about 109 km.Honor Bay has a wide entrance and uneven surface from north to southwest.At the junction of Yuewan Bay and Jinghai Sea, there are tworille , of which the north is calledMcClair Moon Creek(Rimae Maclear), named after Maclair Crater in the east of Moon Bay;The south is calledSocienne Moon Creek(Rimae Sosigenes), named after Sosicheny Crater in the south of Moon Bay.At the west end of Yuewan Bay, the Jinghai Sea stretches to the northwest like a fingerExtension bandIt is almost 100 kilometers long.[1]
