- The blast caused by the shock waves of the Russian meteorite was picked up by infrasound sensors on the other side of the world.
- When a meteoroid hits the Earth’s atmosphere, it may be travelling at 130,000mph.
What are 2 interesting facts about meteoroids?
The oldest particles in a meteorite, calcium-aluminum-rich inclusions from carbonaceous chondrites, have been dated at 4.56 billion years old. Meteorites that originate from asteroids are all ~4.5 billion years old. Meteorites that originate from the Moon range in age from 4.5 to 2.9 billion years old.
What is a fact about meteorites?
Millions of meteoroids travel through the Earth’s atmosphere every day, but most are small and burned up quickly. Very few reach the ground. When a meteoroid hits the atmosphere of the Earth, it can be travelling as fast as 130,000 mph (209,215 km). The buying and selling of meteorite pieces in South Africa is illegal.
What are 3 interesting facts about meteors?
Interesting Meteors Facts: The word meteor comes from a Greek word that means suspended in the air. Meteors can become visible as high as 120 kilometers above Earth.

A meteoroid is an object smaller than 1 metre in diameter. Very small meteoroids are micrometeoroids. They can be as small as a grain of sand. We call anything smaller than 30 micrometres interplanetary dust.
How big is a meteoroid?
Meteoroids are significantly smaller than asteroids, and range in size from small grains to one-meter-wide objects. Objects smaller than this are classified as micrometeoroids or space dust.
What is meteor Facts for Kids?
Small chunks of rock that travel through space are known as meteoroids. If they enter a planet’s atmosphere and burn up, they are then seen as meteors. Sometimes larger pieces of rock survive long enough to crash into a planet’s surface. Space rocks on the Earth’s surface are known as meteorites.
How fast do meteors travel?
The fastest meteors travel at speeds of 71 kilometers (44 miles) per second. The faster and larger the meteor, the brighter and longer it may glow. The smallest meteors only glow for about a second while larger and faster meteors can be visible for up to several minutes.
What is a meteoroid made of?
Most meteoroids are made of silicon and oxygen (minerals called silicates) and heavier metals like nickel and iron. Iron and nickel-iron meteoroids are massive and dense, while stony meteoroids are lighter and more fragile.
Who discovered meteoroids?
In 1807, Yale University chemistry professor Benjamin Silliman investigated a meteorite that fell in Weston, Connecticut. Silliman believed the meteor had a cosmic origin, but meteors did not attract much attention from astronomers until the spectacular meteor storm of November 1833.
