Dynamics of an Asteroid



The astronomers then conducted an analysis called a Bouger correction in order to subtract the gravitational effect of topological features, such as valleys and mountains, from the total gravity field. What is then left is the gravity field hidden beneath the lunar surface, existing within its crust. The Birthstone of Sagittarius is the Lapis Lazuli. Lapis Lazuli is one of the birthstones of this global thinker. Lapis is a stone for the third eye and deepens the connection to your own inner wisdom, intuition and truth. It is an opaque blue stone with the magical power of the earth to help manifest those creative impulses and insights into something tangible. Lapis was one of the sacred stones used in abundance in Egyptian jewelry in combination with gold and coral. The astronomers observed this effect in the upper layer of the lunar crust, termed the megaregolith. This layer is heavily pockmarked by relatively small craters, measuring only 30 kilometers or less in diameter. In contrast, the deeper layers of lunar crust, that are scarred by larger craters, appear not to have been as badly battered, and are, therefore, less porous and fractured.
