Meteors, also known as shooting stars, are objects from space that enter the Earth’s atmosphere and produce a bright streak of light as they burn up due to the friction with the atmosphere. These objects are typically small, ranging from the size of a grain of sand to a boulder, and originate from sources such as comets, asteroids, and other celestial bodies.

Composition of Meteors

Meteors are made up of various materials depending on their source. For example, meteors from comets are typically made up of ice and dust, while those from asteroids are made up of rock and metal. When a meteor enters the Earth’s atmosphere, it heats up and the materials on its surface vaporize, creating the bright streak of light that we see.

Meteor Showers

Meteor showers occur when the Earth passes through a trail of debris left behind by a comet or asteroid. These trails are made up of small particles that burn up in the Earth’s atmosphere, creating a display of shooting stars. Meteor showers are named after the constellation that they appear to radiate from, such as the Perseids, which appear to radiate from the constellation Perseus.

Impact of Meteors

While most meteors burn up completely in the Earth’s atmosphere, larger objects can survive and impact the Earth’s surface. These impacts can create craters and cause significant damage. In fact, it is believed that a meteor impact was responsible for the extinction of the dinosaurs over 65 million years ago.


A meteorite is a meteor that survives the trip through the Earth’s atmosphere and impacts the surface. Meteorites can provide valuable information about the composition of the early Solar System and are studied by scientists to better understand the history and evolution of our Solar System.

Importance of Studying Meteors

Studying meteors is important for understanding the formation and evolution of the Solar System, as well as for predicting and preparing for potential impacts on Earth. Meteors can also provide clues about the presence of water and other resources on other planets and moons in our Solar System.

Meteors are fascinating objects from space that create a dazzling display of light when they burn up in the Earth’s atmosphere. While most meteors are harmless, larger objects can cause significant damage and studying them is important for understanding the history and evolution of our Solar System.
