How Do You Know About Asteroid?

Most people do not know very much about asteroids. And much of what people do know is fiction, not fact!

Many films show asteroids as dangerous space rocks lurking just beyond our orbit, threatens to destroy entire planets in a collision. In reality, asteroids are junk room, and you do not have to worry about an asteroid hits a planet any time soon. Scientists suspect that asteroid press not all our planet more frequently than once every 100 million years! That is why we are safe.

Dinosaurs may not have been so happy, though. The common theory behind their extinction is that an asteroid or comet to Earth 65 million years ago. The impact triggered a massive climate change (places that were hot, cold, and places that were cold hot) weather and violent storms. But do not worry. Even if the scientists are right, and has an asteroid to Earth at the time by their calculations there will be at least another 35 million years until another asteroid come close enough to Strike!

Asteroids are literally waste left over from the formation of our solar system. You float around the room and would create new planets, if they are large enough to emit sufficient gravity. Without sufficient gravity, asteroids can not attract other asteroids, so they never come together in planetary research. And even if all the asteroids in the entire solar system came together, the resulting planet would still be smaller than Erdmond!

It is an asteroid belt (a collection of asteroids close to each other) in our solar system. It is divided into two sections: the inner and outer belt belt. The inner belt consists of the asteroids, less than 250 million km from our sun. The outer belt consists of the asteroid, 250 million km from the sun. The vast majority of asteroids floating in either the inner or outer belt. (Only a few asteroids are outside the asteroid belt.)

There are about 26 large asteroids in our solar system. There are millions of others can be so small they are so large as a single grain of sand! The largest asteroid in our solar system is known as "quaoar", and even that is only one tenth the size of our planet! Another large asteroid was discovered in 2001 called "2001 KX76, which orbits near Pluto. Until the discovery of 2001 KX76 the asteroid "Ceres" was conceived as the second largest asteroid in our solar system. Ceres is now known that the third-largest.
