But where do these meteors come from? In the case of the Lyrids, they come from comet C/1861 G1, which was discovered by American amateur astronomer Albert Thatcher in 1861 (hence its name).

The comet is made of ice, Earth, crystals of carbonaceous material … When it passes close to the Sun, under the influence of heat and radiation, it perishes. The material from which it is sublimated (from the solid state to the gaseous state without passing through the liquid state, editor’s note). It is this that produces the famous tail that we know well and which can reach several tens of millions of kilometres.

The swarms of meteorites are therefore the dust left behind by this tail. When Earth meets its orbit, always at the same time every year, they enter the upper atmosphere at several tens of kilometers per second. Under the influence of friction, they disintegrate, leaving a bright mark for a few seconds. This is what makes a shooting star.
