A small spherical grain or pellet of rock found in meteorites, often containing minerals formed in the early solar system.
From Greek 'chondros' meaning grain or seed; used in meteorite science since the 1800s to describe the fundamental building blocks visible in meteorite structure.
Chondrites (meteorites containing chondres) are literally time capsules from 4.6 billion years ago, showing us what dust grains looked like when planets were just beginning to form.
