Comet: A comet appears as a bright head with a long tail. While investigating the effect of object mass, the height that the objects are dropped from should remain constant. For this we need a bigger unit. This part of the meteor is called a meteorite.

Comets that come into the inner solar system do not live forever! Hence the meteors light up as a streak of light.
