Windows were broken and some buildings were damaged by the pressure wave that resulted. The stone burned up about 30 kilometres above the ground. On February 15, 2013, people who were near the Russian city of Chelyabinsk saw an exceptionally powerful fireball course across the sky.Ī rock between 17 and 20 metres long cruised into the Earth’s atmosphere.

They lit up the sky, and NASA described them as fireballs.Īll these objects burned up in the atmosphere and did no harm. The objects were all over a metre in size and up to almost 20 metres, according to the Earth Observatory. The map below shows meteors that NASA recorded between 19. It’s unusual for rock meteorites that are just a few metres long to form craters, researchers wrote in a study of the incident. This is one of the youngest craters we know of on Earth. It formed a crater with a diameter of 13 metres, Dypvik said. In 2007, a three-metre-long stone fell in Peru. Iron-rich meteorites have a greater chance of falling to the ground and creating craters. Rocks of a few metres will mostly burn up in the atmosphere and don’t do much damage. Objects that are a few metres long are not that unusual.Ī car-sized asteroid hits the atmosphere around once a year, according to NASA. Only 16 meteorites have been found in Norway.Ī shooting star, seen from space. It’s not so easy to find them once they’ve ended their journey on the ground. If the exploding rocks are large enough, their fragments can still plummet down like smaller stones.Įxperts estimate that between 10 and 50 meteorites fall every day, according to the American Meteor Society. Rocks that explode can provide a powerful light show. Wahl is the director of research and Earth observation at the Norwegian Space Agency. “A stone will have a greater chance of burning up and exploding, while one made of iron will survive a longer journey through the atmosphere and will land on the ground,” says Terje Wahl.
Whether any of the stone that comprises the meteoroid survives its journey depends on what it is made of, among other factors. They land on the ground like a meteorite. Meteoroids that are larger, perhaps the size of a basketball or more, can sometimes partially survive the journey through the Earth’s atmosphere.

It happens frequently enough that everyone is likely to experience it once during their lifetime. “I've seen this once and it burns into your memory. These result from stones the size of a fist or larger that hurtle into the atmosphere and have the same effect as a much smaller particle. The large ones are often called fireballs. A strong streak of light flames through the night sky. Sometimes meteors are more impressive than shooting stars. Meteor showers are caused by the Earth passing through the orbit of a comet that has left debris during its journey around the Sun. The showers come at fixed times, such as the Perseid meteor shower in August. Sometimes you can see more shooting stars than usual, in an event that is called a meteor shower. When the material cools, it becomes a solid again and rains down on the Earth, according to an article from Videnskab.dk. The surrounding air becomes so hot that it lights up. These small particles crash into air molecules in the atmosphere at breakneck speed, burn up and turn into gas. They usually weigh around one gram and are the size of a grain of sand or a pea. The objects that create shooting stars are smaller than you might think. Small particles fall into the atmosphere all the time. When they hit the atmosphere and light up, they are called meteors.
