Meteors

Meteors, sometimes called Shooting Stars, are not stars at all, but small rocks burning up as they enter the Earth's atmosphere.

Every day, around 100 tonnes of rocks and dust enter our atmosphere. Luckily, most of these objects are so small that they burn up completely before reaching the ground, and do not represent a danger.

Although you can see a few meteors on any clear night, the best time to observe them is during a big Meteor Shower. These can last for several nights and occur when the Earth passes through the trail of debris left behind by a comet or asteroid. During the peak of a good shower, you may see as many as 100 meteors in an hour, however, on a typical night, you can expect to see around 6 meteors per hour. Extremely bright meteors often leave an “afterglow” along their trail, called a train.

Some rocks are big enough that they do not get totally burnt up. These fall all the way down to the surface and are called Meteorites.

Meteorites are mainly pieces of asteroids leftover from when the Solar System formed, but some break off from comets, or have even found their way to Earth following large impacts on the Moon and Mars. Meteorites have a lot more metals in them than rocks on Earth, this makes them more dense - heavier than we expect based on the size of them.

 

Plan your meteor spotting

You need dark skies! The less light around you the better, so try to move well away from buildings and street lights. Also, check the phase of the Moon! A bright full Moon will spoil your chances of seeing meteors. You can check today's phase of the Moon on our homepage. Make sure to wear warm clothes and be patient, you might not see any on your first try!
