Orconuma meteorite
The Orconuma meteorite is a meteorite that was discovered in the Philippines, and it is one of six meteorites from the Philippines listed in the Meteoritical Society's Bulletin database.[1] The meteorite is thought to have formed about 4.6 billion years ago.
Discovery[edit]
The Orconuma meteorite fell to Earth 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[edit]
The Orconuma meteorite is classified as an H3-4 chondrite. 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.[4]
