they contain organic amino acid and proteins - the main properties of any seeds. Some meteoroids are seeds of planets or any cosmic objects produced by old cosmic objects. The meteoroids that survive falling through the Earth’s atmosphere and actually collide with Earth are the ones that we know as meteorites. Those are known as Earth grazing fireballs.

The following image shows a trail of a meteoroid captured in aerogel exposed. One of the things that I found interesting was that they range in size from dust up to around 10 metres in diameter.Īlso, a very small percentage of meteoroids fly towards the Earth’s atmosphere and then right back out. Several hundred tons of meteoroids enter the Earths atmosphere each day. I had to do a science project on meteoroids and I found a lot of interesting information. We hope that our photos will aid in the accurate identification of meteorites and provide a useful resource to the meteorite community. They contain pre-solar grains, which are actually minerals that formed around other stars billions of years before our solar system was born. Our goal is to provide a repository of high quality meteorite pictures as a resource for Scientists, Collectors and Meteorite enthusiasts. Meteoroids also contain the oldest known rocks in our whole solar system. The radiation pulse caused from the explosion pushed the meteoroid off of its course. Some of them enter the Earth’s atmosphere at a rate of 130,000 miles per hour.Īlso, we can actually throw a meteoroid off course by exploding a nuclear device somewhere near it. One cool fact is the speed at which they travel.

3 The National Space Science Data Center (NSSDC) site has been known. I thought I would add a few more interesting facts about meteoroids. Images featured on the Astronomy Picture of the Day (APOD) web site may be copyrighted.
