Meteorite, meteor, meteoroid are all different. Here's how to tell which is which!

In the past several days, multiple meteor sightings have been reported across the area and have grabbed national attention. But, did you know there is a process that takes place before you see the flash of light?

“In space there are comets, asteroids and smaller obits of debris or space rock called meteoroids,” Storm Center 7 Meteorologist Kirstie Zontini said. “If these meteoroids enter the Earth's atmosphere they heat up during the trip producing a bright tail.”

“A meteor as bright as Venus is known as a fireball, a bolide is a big meteoroid that actually explodes when traveling through the atmosphere producing a bright flash! If any piece of the space rock actually survives the trip and lands on earth it is called a meteorite,” Zontini said.
