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.
Discovered on March 31, 2005, by a team of planetary scientists led by Dr. Michael E. Brown of the California Institute of Technology (Caltech) in Pasadena, Makemake was initially dubbed 2005 FY 9, when Dr. Brown and his colleagues, announced its discovery on July 29, 2005. The team of astronomers had used Caltech's Palomar Observatory near San Diego to make their discovery of this icy dwarf planet, that was later given the minor-planet number of 136472. Makemake was classified as a dwarf planet by the International Astronomical Union (IAU) in July 2008. Dr. Brown's team of astronomers had originally planned to delay announcing their discoveries of the bright, icy denizens of the Kuiper Belt--Makemake and its sister world Eris--until additional calculations and observations were complete. However, they went on to announce them both on July 29, 2005, when the discovery of Haumea--another large icy denizen of the outer limits of our Solar System that they had been watching--was announced amidst considerable controversy on July 27, 2005, by a different team of planetary scientists from Spain.
Furthermore, the icy stuff that collected on Methone's surface could even be more lightweight than that which lies beneath. It is possible that such fluffy, snowy, stuff can actually flow--at least over long periods of thousands to millions of years--thus filling in the tell-tale scars of impact craters.
