hondrula

hondrula

Roughly spherical objects found in a type of meteorite called chondrites. Most chondrules are 0. 5 to 2 millimeters in size and are composed of olivine and pyroxene, with smaller amounts of glass and iron-nickel metal. The shapes of the mineral grains in them indicate that chondrules were once molten droplets floating freely in space.
