What is the difference between a meteor and an asteroid?

From NCERT Asked by Anonymous from Seattle, United States 23 Oct 2026, 9:31 PM IST Updated

In one line

A meteor is a streak of light seen when a space rock burns in Earth's sky, while an asteroid is a rocky body that orbits the Sun.

The rule

Asteroids are small rocky objects that orbit the Sun, mostly found between Mars and Jupiter. Meteors are flashes of light seen when small space rocks enter Earth's atmosphere and burn up.

Let's understand it simply

Imagine you are playing cricket and a small stone is lying on the ground. That stone is like an asteroid—it is just sitting there, moving around the Sun in space. Now, imagine someone throws a small pebble very fast and it hits the ground, making a spark. That spark is like a meteor—it is the flash of light we see when a small space rock enters Earth's air and burns up.

How it works

  1. Asteroids are big rocks floating in space, mostly between Mars and Jupiter.
  2. Sometimes, a small piece breaks off from an asteroid.
  3. If this piece travels towards Earth and enters our atmosphere, it gets very hot due to friction (rubbing against air).
  4. This hot, burning rock makes a bright streak in the sky—this is a meteor.
  5. If the rock is big enough and does not burn completely, it can fall to the ground. That leftover piece is called a meteorite.

The story behind it

Scientists have studied asteroids for a long time to learn about the early Solar System. The word "meteor" comes from a Greek word meaning "high in the air." People have watched meteors (also called shooting stars) for thousands of years, often making wishes when they see one.

Where you see it in real life

  • Asteroid Belt: Between Mars and Jupiter, there are thousands of asteroids orbiting the Sun.
  • Meteor Showers: On some nights, you can see many meteors (shooting stars) in the sky, especially during events like the Perseid meteor shower.
  • Meteorite in Museums: Some museums in India have real meteorites you can touch—they are pieces of space rock that survived the fall to Earth.
  • News Reports: Sometimes, newspapers report when a meteorite lands in a village or city.

Why it matters

  • Asteroids can tell us about how the planets formed.
  • Meteors help us understand what happens when space rocks hit Earth's atmosphere.
  • Meteorites can bring rare metals and clues about space to Earth.
  • Knowing about asteroids is important for protecting Earth from big impacts in the future.

Common mistakes

  • Thinking a meteor is a rock in space—it is actually the flash of light, not the rock itself.
  • Mixing up meteor, meteorite, and asteroid. Remember: asteroid = rock in space, meteor = flash in sky, meteorite = rock that lands on Earth.

Remember it

Asteroid = space rock; Meteor = shooting star (flash in sky).

Check yourself

Where are most asteroids found?

Between Mars and Jupiter, in the asteroid belt.

What do we call the bright streak of light when a space rock burns up in the sky?

A meteor.

Why do meteors appear as flashes of light?

Because the rock burns due to friction with Earth's atmosphere.

If a piece of space rock lands on Earth, what is it called?

A meteorite, because it survived the fall and reached the ground.

Quick recap

  • Asteroids are rocky objects orbiting the Sun.
  • Meteors are flashes of light when space rocks burn in Earth's atmosphere.
  • Asteroids are found mainly between Mars and Jupiter.
  • A meteor is not the rock, but the streak of light.
  • Meteorites are pieces that reach the ground.
