[[Ordinary chondrite]]s are by far the most common type of meteorite to fall to Earth: about 80% of all meteorites and over 90% of chondrites are ordinary chondrites.<ref name="lunar"/> They contain abundant chondrules, sparse matrix (10–15% of the rock), few refractory inclusions, and variable amounts of Fe–Ni metal and [[troilite]] (FeS). Their chondrules are generally in the range of 0.5 to 1&nbsp;mm in diameter. Ordinary chondrites are distinguished chemically by their depletions in [[refractory]] [[Goldschmidt classification|lithophile]] elements, such as Ca, Al, Ti, and [[rare earth elements|rare earths]], relative to Si, and isotopically by their unusually high <sup>17</sup>O/<sup>16</sup>O ratios relative to <sup>18</sup>O/<sup>16</sup>O compared to Earth rocks.

Most, but not all, ordinary chondrites have experienced significant degrees of metamorphism, having reached temperatures well above 500&nbsp;°C on the parent asteroids. They are divided into three groups, which have different amounts of metal and different amounts of total iron: 
*[[H chondrite]] have high total iron and high metallic Fe (15–20% Fe–Ni metal by mass<ref>{{cite web |last=Korotev |first=Randy |title=metal, iron, & nickel in meteorites 1 |url=http://meteorites.wustl.edu/id/metal.htm |url-status=dead |archive-url=https://web.archive.org/web/20190702084637/http://meteorites.wustl.edu/id/metal.htm |archive-date=2 July 2019 |access-date=1 July 2010 |website=meteorites.wustl.edu |publisher=[[Washington University in St. Louis]]}}</ref>), and smaller chondrules than L and LL chondrites. They are formed of bronzite, olivine, pyroxene, plagioclase, metals and sulfides and ~42% of ordinary chondrite falls belong to this group ''(see [[Meteorite fall statistics]])''.
*[[L chondrite]]s have low total iron contents (including 7–11% Fe–Ni metal by mass). ~46% of ordinary chondrite falls belong to this group, which makes them the most common type of meteorite to fall on Earth.
*[[LL chondrite]]s have low total iron and low metal contents (3–5% Fe–Ni metal by mass of which 2% is metallic Fe and they also contain bronzite, [[oligoclase]] and olivine).<ref name="clas"/> Only 1 in 10 ordinary chondrite falls belong to this group.

An example of this group is the [[NWA 869]] meteorite.
