On January 10 2026, residents near Los Angeles witnessed a dramatic streak of flame cutting across the night sky. Local station ABC7 shared footage that initially sparked speculation about a rocket launch or a falling Starlink satellite. Within hours, the American Meteor Society (AMS) confirmed the sighting was a genuine fireball.
A fireball is a meteor that outshines any star visible from Earth. Astronomers gauge brightness using the stellar magnitude scale: the Sun is −26.7, Venus tops at −4.6, and the brightest star, Sirius, is −1.46. Fireballs typically register between −5 and −10, eclipsing Venus and often approaching the brightness of the full moon (−13). Such luminosity indicates an impactor at least the size of a baseball, with the most luminous events coming from meteoroids the size of a small car.
Space is littered with debris—from comet tails to asteroid fragments—so when a piece of this material enters Earth’s atmosphere, it becomes a meteor. The rapid friction causes the material to vaporize and glow, a process that protects life below by burning up most incoming rock and metal. While most meteors are tiny, a fireball requires a larger body, roughly the mass of a baseball or greater, to achieve its extraordinary brightness. Occasionally, fireballs explode mid‑air, producing a bolide that releases a sudden burst of energy.
When a fireball survives atmospheric passage, it can leave behind meteorites that reach the ground. Recovering these fragments provides invaluable scientific insight into the composition of our solar system. Although fireballs are common, finding a meteorite from one is still a rare event, sparking excitement in the scientific community.

Contrary to popular belief, fireballs occur daily. Thousands of meteoroids enter the atmosphere every day, but only a fraction ignite as bright fireballs. Many fall over the oceans—roughly 75 % of Earth’s surface—making them difficult to observe. During daylight, their glow is masked by the Sun, and the brief, 3–5 second duration of a fireball’s display demands precise timing and location for an observer to witness it.
Fireballs also travel at astonishing speeds, often exceeding 100 000 mph upon atmospheric entry. Even as they decelerate, they can still reach speeds above 760 mph near the ground, producing a sonic boom that typically arrives a few minutes after the event.
