What factors influence the Widmansttten pattern in iron meteorites? Before entering the earth's atmosphere the small objects in the space are meteoroids. At that speed, the friction between the meteor and the air causes them to burn up high in the Earths atmosphere, and we see a flash of light, also known as a shooting star. We usually see only the large ones travel down towards the horizon while the small ones are burnt up long before that (giving the impression of coming from the horizon).

If you hear one, see coloured flashing lights on it, or it changes direction suddenly, then youve spotted an aircraft, a bird or Superman.

A meteor shower happens when the Earth goes through a region of space that is especially filled with dust and chunks of rock. How big was asteroid that killed dinosaurs? Meteors are the streaks of light we see at night as small meteoroids burns up passing through our atmosphere (1) Shooting stars are small pieces of rock or dust that hit Earths atmosphere from space (2). How are meteors and Shooting Stars related to each other? One of the most beautiful aspects of astronomy and stargazing is looking up to see shooting stars (sometimes referred to as falling stars) flying across the night sky. Because the largest meteoroids have a much higher meteoric iron content, they are more likely to impact the Earths surface. A meteor, or shooting star, will move in less than a fraction of a second across the sky. Sometimes they are so big that they dont burn up completely, but parts of them hit the earth. 2.

While the smaller meteoroids will burn at high altitudes in the atmosphere, the larger and heavier ones contain a large core made of iron which cannot be vaporized by atmospheric friction (also known as atmospheric drag). When stars are in the midst of their normal life cycles, their hot lower layers exert enough pressure to support the tremendous weight of their upper layers.
