Juvinas is an achondrite meteorite that fell in Ardèche, France, on June 15, 1821.
Eucrites are the most common type of achondrite meteorite falls (vs. finds) and are believed to form from cooling of magma on the surface of Asteroid 4-Vesta; the number 4 refers to Vesta being the fourth asteroid ever discovered, in March of 1807, by German astronomer Heinrich Wilhelm Olbers.
In 2007, NASA launched the Dawn mission to study Vesta and the dwarf planet Ceres, and to provide insight into the formation and evolution of solid bodies in the early Solar System using a visible camera, a visible and infrared mapping spectrometer, and a gamma ray and neutron spectrometer. The extremely detailed images Dawn captured of Vesta's surface enabled the compilation of high-resolution global geological and tectonic maps of Vesta, published in the journal Icarus by a scientific team led by ASU School of Earth and Space Exploration Associate Research Professor Dr. David Williams.
The Juvinas meteorite is named for the French commune, or municipality, in which its fall was witnessed.
