Asteroids, which are typically rocky or metallic and larger than one meter, orbit the Sun and have remained relatively unchanged, serving as windows into the early solar system. Smaller objects, known as meteoroids, become meteors when they burn up in the atmosphere. If they survive the fiery descent and hit the ground, they are termed meteorites.

Comets, composed of ice and dust, originate in the outer reaches of the solar system. When fragments of these comets enter our atmosphere at high speeds, they can produce dazzling displays. This was the case with the comet fragment that Milena Refacho recorded—a piece blazing through the sky over the Atlantic Ocean and creating a spectacular blue trail.
