Meteorite
What is Meteorite?
A meteorite is a solid piece of debris from an object, such as a comet, asteroid, or meteoroid, that originates in outer space and survives its passage through the atmosphere to reach the surface of a planet or moon. Meteorites are classified into three broad categories: stony meteorites, iron meteorites, and stony-iron meteorites, based on their composition. They provide valuable information about the early solar system.

- Refractive Index
- Variable, depending on the minerals present. Generally high due to the presence of iron and nickel.
- Birefringence
- Not applicable, as meteorites are not a single mineral.
- Pleochroism
- Not applicable, as meteorites are not a single mineral.
- Optical Character
- Not applicable, as meteorites are not a single mineral.
- Dispersion
- Not applicable, as meteorites are not a single mineral.
