Chondrules in the chondrite classification Grassland. A millimeter scale is shown. Chondrules in the Carbonaceous Chondrite NWA 13887. A chondrule (from Ancient Greek χόνδρος chondros, grain) is a round grain found in a chondrite. Chondrules form as molten or partially molten droplets in space before being accreted to their parent asteroids.

The 1 in C1 stands for the type 1 meteorites in the older classification scheme of Van Schmus-Wood, [4] still used for petrography. Petrographic type-1 meteorites, by definition, have no fully-visible chondrules .
VdB 1 (LBN 578, or Magakian 3) is a small reflection nebula in the constellation Cassiopeia. It lies a few arcminutes to the south-east of the bright yellow-hued giant star Beta Cassiopeiae, officially named Caph. VdB 1 lies about 1,600 light-years away. [1] [2] Close to VdB 1 is the dark nebula LDN 1265. It is barely visible due to the ...
The expansion rate of different portions of the nebula varies from 10 km/s to at least 30 km/s, leading to age estimates of 78,500 - 236,000 years. The nebula has been studied at radio and x-ray wavelengths, but it is still unclear whether it was produced at the class O main sequence stage of development, as a red supergiant , luminous blue ...
LL chondrites contain the largest chondrules of the ordinary chondrite groups, averaging around 1 millimetre (0.039 in) diameter.. The LL group includes many of the most primitive ordinary chondrites, including the well-studied Semarkona (type 3.0) chondrite.
