A meteor, commonly known as a "shooting star" or "falling star," is a streak of light in the sky produced by a meteoroid as it burns up entering Earth's atmosphere. Meteoroids are small fragments of rock or metal that originate from comets or asteroids. When these objects orbit the Sun, they sometimes collide with Earth's atmosphere at speeds ranging from 11 to 72 kilometers per second. The intense friction and heat caused by the entry into Earth's atmosphere at such high speeds vaporize most meteoroids, creating the brilliant light commonly observed from the ground.
The light phenomenon we observe is technically called a meteor, while the actual rock in space before it hits the atmosphere is known as a meteoroid. If a meteoroid survives its fiery passage through the atmosphere and lands on Earth, it is then termed a meteorite. This classification helps scientists and astronomers discuss and study these extraterrestrial objects more precisely. The study of meteors is vital as it contributes to our understanding of the early solar system, providing clues about the composition of other celestial bodies and Earth's own materials.
Most meteors are observed as part of meteor showers, which occur when Earth passes through a trail of debris left by a comet. Perseids and Geminids are among the most famous annual meteor showers, known for their vibrant and numerous meteors. These events are eagerly anticipated by astronomers and skywatchers alike for their spectacular displays. Meteor showers provide an ideal opportunity for the general public to witness the dynamics of our solar system in real-time.
In addition to their scientific value, meteors hold various cultural significances across different societies. Many ancient cultures interpreted meteor showers as omens or messages from the gods. Today, they are often featured in art and literature, symbolizing both transient beauty and the ephemeral nature of life on Earth. The fascination with meteors continues to inspire both professional and amateur astronomers to look up at the night sky in wonder, continuing humanity's age-old practice of celestial observation.
