What is the difference between a meteor, meteoroid, and meteorite?

A meteor, meteoroid, and meteorite are all related to space debris, but they differ in terms of their location and size. A meteoroid is a small piece of rock or debris in space, typically less than 10 meters in diameter, that orbits the sun. When a meteoroid enters the Earth's atmosphere, it heats up and produces a streak of light called a meteor, also known as a shooting star or falling star. If the meteoroid survives the trip through the atmosphere and lands on the Earth's surface, it is then called a meteorite.

Meteors are usually seen as streaks of light in the sky, and are often associated with meteor showers. Meteoroids are constantly bombarding the Earth, but most are small enough to burn up completely in the atmosphere before they reach the ground. Larger meteoroids may survive the trip through the atmosphere and strike the Earth's surface, causing impact craters.

The study of meteoroids, meteors, and meteorites is important to astronomers, as it provides information about the composition and history of our solar system. Meteorites in particular are valuable as they contain information about the early history of the solar system, and have been used to study the formation of the planets.

A meteoroid is a small solid object, such as a piece of an asteroid or comet, in outer space. When meteoroids enter Earth's atmosphere at high speed, they burn up and become meteors. If a meteor survives its fiery journey through the atmosphere and lands on the ground, it is called a meteorite.

• Meteoroid: A meteoroid is a small solid object, such as a piece of an asteroid or comet, in outer space. Meteoroids range in size from dust grains to small asteroids.
• Meteor: A meteor is the streak of light produced by a meteoroid as it enters Earth's atmosphere and heats up due to friction. Meteors are often called "shooting stars."
• Meteorite: A meteorite is a meteoroid that survives its fiery journey through the atmosphere and lands on the ground. Meteorites can be made of a variety of materials, including rock, iron, and stony-iron.

Here is a diagram that summarizes the differences between meteors, meteoroids, and meteorites:
