The meteor dates to the early formation of the solar system 4 to 5 billion years ago. It was probably about the size of a minivan when it entered the Earth's atmosphere on April 22, 2012 with a loud boom. It was seen from Sacramento, California, to Las Vegas and parts of northern Nevada.
Field Museum curator Philipp Heck said Wednesday that the institution will preserve the meteorite for "future generations of scientists who will be armed with analytical tools which we can only dream of today."
Scientists plan to use the pieces for research. They used a CT scan to determine the meteor's age and chemical composition.
Private collector Robert Haag owned the meteorite and contacted Meenakshi Wadhwa, director of Arizona State University's Center for Meteorite Studies. She contacted the other institutions to discuss sharing the piece.
