The Orconuma Meteorite is a significant meteorite that fell on Earth and was discovered in the Philippines. It is one of the six meteorites from the Philippines listed in the Meteoritical Society’s Bulletin Database.[1] This space rock is one of the first solid materials to form from the earliest days of our solar system, about 4.6 billion years ago.

Discovery

The Orconuma Meteorite fell on March 7, 2011, in Orconuma, Bongabong, Oriental Mindoro.[2] It was discovered by three farmers, Fredo Manzano, Edgar Francisco Sr., and Enrico Camacho, Jr., who found the meteorite in the middle of a field. They initially hid and stored the specimen for nine years before it was uncovered.[3]

Classification

The Orconuma Meteorite is classified as an H3-4 chondrite.[4] This classification indicates that it is a type of stony meteorite that is rich in olivine and pyroxene, and it originated from the asteroid belt. The H3-4 classification also suggests that it underwent minimal thermal metamorphism on its parent body.

Current Status

The Orconuma Meteorite is now part of the National Geological and Paleontological Collections of the National Museum in the Philippines. It is the first-ever meteorite specimen to be included in these collections.
