Asteroids, comets, and meteors are chunks of rock, ice, and metal left over from the formation of our solar system 4.6 billion years ago. They are a lot like a fossil record of our early solar system. There are currently about 1.3 million known asteroids, and more than 3,800 known comets. Some rocks are intermediate between mafic and felsic, and these rocks are often composed of light and dark minerals. The grain size depends on how quickly the magma or lava has cooled. If the magma cooled slowly, the individual grains had time to grow and can be seen with the eye. These rocks have a coarse-grained, or phaneritic, texture.

Holohyaline rocks are entirely glassy, whereas porphyritic rocks have two or more sizes of grains within a finer-grained mass. (See also igneous rock: textural features.) Sedimentary rock texture. Sedimentary rock texture is determined by the size, shape, and fabric (grain packing and orientation) of the discrete grains or particles in the rock.
