You're outside at night. A bright streak cuts across the sky. It lasts a second. Maybe two. You make a wish. But that streak wasn't a star at all. It was a rock. A tiny piece of space dust or gravel, no bigger than a grain of sand, slamming into Earth's atmosphere at tens of thousands of miles per hour. The air in front of it compresses. It heats up. It glows. That glow is what you see — a meteor. Most burn up completely. A few survive the trip and hit the ground. Those become meteorites. Every day, about 48 tons of this stuff falls on Earth. Most of it you never notice. But on certain nights, when Earth crosses a comet's old trail, the sky puts on a show. We call those meteor showers. The Perseids in August. The Geminids in December. They're not stars falling. They're the solar system's leftovers, burning up overhead.
“The iron in that shooting star's glow was forged in a dying star billions of years before Earth existed — and now it's part of our atmosphere, our soil, maybe even your blood.”

The term 'shooting star' is a misnomer. What we see is a meteoroid — a bit of rock or dust in space, ranging from sand-grain size to a small pebble — hitting Earth's atmosphere at high speed. The friction with air molecules heats it to incandescence, creating a brief streak of light. That streak is technically called a meteor. The object itself is tiny. Most are no bigger than a grain of sand. They vaporize completely before reaching the ground.
Earth is constantly sweeping up material left over from the solar system's formation. Most of it is dust — micrometeoroids too small to see. But the total mass adds up. NASA and other agencies estimate roughly 48 metric tons (about 105,000 pounds) of extraterrestrial material enters our atmosphere daily. The vast majority burns up harmlessly. Only the larger pieces create visible meteors. Even fewer survive to become meteorites.
Comets are dirty snowballs. As they orbit the Sun, they shed dust and rock along their path. These debris trails persist for centuries. Each year, Earth's orbit crosses several of these trails. When we plow through one, the rate of meteors jumps dramatically — dozens or hundreds per hour. The shower gets its name from the constellation where the meteors appear to radiate. The Perseids come from comet Swift-Tuttle. The Geminids are unusual — they come from an asteroid, 3200 Phaethon, that behaves like a comet.
The color of a meteor's glow tells you what it's made of. Magnesium produces blue-green. Iron gives yellow. Sodium creates orange-yellow. Ionized calcium adds violet. The surrounding air also contributes — nitrogen and oxygen can make the trail look red. These colors are often faint to the naked eye but show up clearly in photographs and video. A single meteor can change color as it burns, revealing layers of different minerals.
Three terms track the same object through its journey. In space, it's a meteoroid. While burning in the atmosphere, the light streak is a meteor. If any piece lands on Earth, that piece is a meteorite. Most meteoroids are too small and fragile — they disintegrate completely. Meteorites are rare. They're also scientifically valuable: they're essentially free samples of asteroids, the Moon, or even Mars, delivered to us without a space mission.

Perspectives
Enter a viewpoint. Notice what it reveals, what it leaves out, and whether it changes the question for you.
To a planetary scientist, every meteor is data. The light curve — how bright it gets, how fast it fades — reveals the object's size, speed, and structure. The spectrum of its light reveals composition. Networks of cameras (like NASA's All-Sky Fireball Network) triangulate trajectories to calculate orbits. This tells us where the debris came from: which comet, which asteroid family. Some meteors are interstellar — visitors from other star systems. The first confirmed one, 'Oumuamua, wasn't a meteor but proved such objects exist. A meteorite in hand is even better. We can date it, measure its exposure to cosmic rays, and reconstruct the history of the solar system. The Chelyabinsk meteor in 2013 was recorded by hundreds of dashcams. Scientists used those videos to reconstruct its orbit and origin in the asteroid belt. Science turns a fleeting streak into a window on deep time.
