How do meteors form?

Origin of meteors

Meteors are created from meteoroid debris, often left behind after a comet passes by the Sun. As the comet passes, the ice and dust on its surface evaporates, creating a cloud of debris that floats in space.

When the Earth moves into the right area of ​​these debris fields – usually at the same time each year – the dust particles are sucked into Earth's atmosphere.

Spectacular luminous phenomenon

These pieces of dust or rock, though very small, when rushing into the atmosphere at speeds of up to 11–72 km/s, they collide strongly with the air, creating heat and burning brightly. That is the streak of light we call a meteor.

Most meteors burn up completely before hitting the ground. But if a piece is large enough and doesn't burn up completely, the remaining piece that falls to the ground is called a meteorite.

When can you see shooting stars?

Meteors can appear sporadically at any time, but the best times to see them are during the regular meteor showers. Some famous showers are the Perseids (August), Geminids (December), or Quadrantids (January).

These are times when the Earth passes through the dust cloud left behind by the comet, causing the number of meteors to skyrocket – possibly up to hundreds per hour.

Meteor: a cosmic wonder in the night sky

Though they are just tiny bits of space dust, meteors are still one of the most spectacular sights in the sky. Not only are they beautiful, they also hold valuable clues that help scientists understand the history of the Solar System and the universe.

Have you ever made a wish when you saw a shooting star? Perhaps the magic lies not only in the light, but also in the millions of years it has traveled to reach our night sky.
