Loading contentThe small bodies that reach the ground — the meteorites that fall from asteroids, Mars, and the Moon, the fireballs that announce their arrival, and the craters they leave behind. The capstone of the small-bodies trilogy, connected through the Knowledge Graph to the asteroids and comets they come from.
Every meteorite modelled in the encyclopedia, across all classes.
20 entriesMeteorites seen to fall and then recovered — the freshest, least-altered samples.
12 entriesMeteorites discovered on the ground without a witnessed fall.
8 entriesMeteorites recovered from twenty-first-century falls, several traced to their orbits by camera networks.
4 entriesThe most massive meteorites ever recovered, led by the ~60-tonne Hoba iron.
5 entriesPrimitive, carbon- and water-rich meteorites carrying the organic building blocks of the Solar System.
6 entriesThe chondrites and achondrites — meteorites made mostly of rock.
13 entriesDense nickel-iron meteorites from the cores of shattered asteroids.
5 entriesRocks blasted off Mars and delivered to Earth, identified by trapped Martian atmosphere.
2 entriesPieces of the Moon flung to Earth by impacts, matched to the Apollo samples.
1 entriesThe howardite–eucrite–diogenite meteorites, pieces of the asteroid Vesta's crust.
1 entriesExceptionally bright meteors and the bolides that detonate in the atmosphere.
2 entriesFireballs bright enough to explode — the airbursts of Peekskill and the Bering Sea.
2 entriesThe craters left on Earth by past impacts, from young Meteor Crater to ancient Vredefort.
4 entriesThe strewn fields where the fragments of a single fall are recovered.
2 entriesThe damaging airbursts and the objects that reached the ground — why near-Earth objects are tracked.
3 entriesThe four great classes and their groups.

Each meteorite, class, group, fireball, impact structure, and recovery site is a first-class knowledge-graph entity resolved through the Scientific Data Engine. Classifications and fall data come from the Meteoritical Bulletin Database. The parent bodies — the asteroid Vesta, Mars, and the Moon — the impact events, and the meteor showers are the platform's existing entities, reused and never duplicated. This encyclopedia detects no live fireballs; for observing, see the Live Sky meteor showers. Unknown values are left blank. See source quality.
