Meteoroid: meaning, definitions and examples

Etymology

• The term comes from the Greek word 'meteoros,' meaning 'high in the air,' reflecting where these objects travel.
• Initially, the term referred to anything that appeared to be falling from the sky, adapted later to specific celestial objects.
• The suffix '-oid' indicates a resemblance, hence describing these fragments as 'rock-like' objects in space.

Science

• Meteoroids range in size from tiny grains to objects as large as a boulder, depending on where they come from in the solar system.
• Most meteoroids come from comets and asteroids, which leave trails of debris that can lead to meteor showers when Earth passes through them.
• When a meteoroid enters Earth's atmosphere and burns up, it creates a bright flash of light called a meteor – often referred to as a shooting star.

Space Exploration

• Spacecraft, like the Mars rovers, have been designed to study meteoroids and understand their role in forming planets and other celestial bodies.
• NASA's Perseverance rover collects samples that will help scientists learn about the history of meteoroids on Mars and their implications for life.
• Meteoroids can pose a risk to spacecraft, which is why scientists carefully track larger objects in space to prevent collisions.

Pop Culture

• Meteoroids and meteors are often depicted in movies and books as dramatic events, such as in the film 'Armageddon' where asteroids threaten Earth.
• The idea of meteors hitting Earth often inspires sci-fi stories where life is affected, showcasing humanity's fascination with outer space risks.
• Meteor showers are celebrated events in popular culture, with many people hosting viewing parties to watch these natural light shows.

Astronomy

• Astronomers classify meteoroids based on their size: those less than 1 meter are typically called meteoroids, while larger ones are classified as asteroids.
• Tracking meteoroids helps scientists understand the composition and evolution of the solar system over billions of years.
• Meteoroids can provide valuable information about the building blocks of planets, as they often contain minerals and organic compounds.
