This cache is Part of the Caches Across the Solar System series in Southern California, which will take visitors to scale representations of the Planets, Dwarf Planets, Moons, and Other Objects of the Solar System, with the Great Park Balloon representing the Sun. Find at least 6 CASS Caches, stamp your passport, and turn it in at the Signal's Island Block Party (GCAXN0B) for prizes! This cache doesn't have a stamp it has a code word
Here's some info about Moons:
“The Moon is Earth's only natural satellite. It orbits Earth at an average distance of 384399 km (238,854 mi; about 30 times Earth's diameter). The Moon's orbital period (lunar month) and rotation period (lunar day) are synchronized by Earth's gravitational pull at 29.5 Earth days, making the same side of the Moon always face Earth. The Moon's pull on Earth is the main driver of Earth's tides.
In geophysical terms, the Moon is a planetary-mass object or satellite planet. Its mass is 1.2% that of the Earth, and its diameter is 3,474 km (2,159 mi), roughly one-quarter of Earth's (about as wide as the contiguous United States). Within the Solar System, it is the largest and most massive satellite of its parent planet, the fifth-largest and fifth-most massive moon overall, and larger and more massive than all known dwarf planets.[17] Its surface gravity is about one-sixth of Earth's, about half that of Mars, and the second-highest among all moons in the Solar System, after Jupiter's moon Io. The body of the Moon is differentiated and terrestrial, with no significant hydrosphere, atmosphere, or magnetic field. The lunar surface is covered in lunar dust and marked by mountains, impact craters, their ejecta, ray-like streaks, rilles, and, mostly on the near side of the Moon, by dark maria ('seas'), which are plains of cooled lava. These maria were formed when molten lava flowed into ancient impact basins. The Moon formed 4.51 billion years ago, not long after Earth's formation, out of the debris from a giant impact between Earth and a hypothesized Mars-sized body called Theia.
The Moon is, except when passing through Earth's shadow during a lunar eclipse, always illuminated by the Sun, but from Earth, the visible illumination shifts during its orbit, producing the lunar phases.[18] The Moon is the brightest celestial object in Earth's night sky. This is mainly due to its large angular diameter, while the reflectance of the lunar surface is comparable to that of asphalt. The apparent size is nearly the same as that of the Sun, allowing it to cover the Sun completely during a total solar eclipse. From Earth, about 59% of the lunar surface is visible due to cyclical shifts in perspective (libration), making parts of the far side of the Moon visible”(Wikipedia).
