Not all meteors come from comets.
The word “meteor” specifies a space object that enters Earth’s atmosphere, but burns up before hitting the planet’s surface.
They can come from anywhere in space, since meteors are simply debris.
The solar system is full of chunks of rock and metal, left over from the creation of the planets and various collisions, as well as burned-out or broken-up comets.
Many of these objects often end up on a collision course with earth and become meteors and meteoroids.
