What is a shooting star?

Have you ever look to sky and see a streak of light? Well, in fact those are not stars, actually, they are meteoroids. The light you can see is the result of the meteoroid that burned up as enters the planet’s atmosphere, trying to make their way through to arrive to the Earth.

A meteoroid is a small particle from a comet or asteroid.  Many meteors appearing seconds or minutes apart that seem to fall from the same point in the sky are called a meteor shower.

They have a wide range of sizes, from dust particles to around 10 metres in diameter (although larger objects are usually referred to as asteroids).

The fastest meteoroids travel through the solar system at a speed of around 42 kilometres per second (26 miles per second).

Around 15,000 tonnes of meteoroids, micrometeoroids and different forms of space dust enter Earth’s atmosphere each year!

If a meteor survives the plunge through the atmosphere and lands on the surface, it’s known as a meteorite.
