Scientists classify small objects in the solar system by size, shape, and composition

The first variable that is used to classify stars is its ionization state which can measure the photosphere's temperature and density. This information is gathered by splitting the light from a star with a prism and observing the resulting spectrum that includes absorption lines. Luminosity is another variable used; it is based on the width of absorption lines.
Meteorologists classify tornadoes on the Enhanced Fujita Scale based on the severity of the damage they cause with EF0 being the weakest and EF5 being the strongest.
