The amount of time they spend shooting through the atmosphere is too brief to warm the rock completely, and so when they land, they are not hot enough to set anything on fire because of the rock’s temperature. While meteoroids are still in space, they are cold. (5, 6)Īre meteorites on fire when they crash into earth? No. Meteorites do contain small amounts of radioactive particles that are quickly lost, but they last such a short amount of time and are in such trace amounts that they are not dangerous. (6)Īre meteorites radioactive? Mostly no. This iron causes them to be more dense than earth rocks of the same size. The same thing that causes meteorites to be magnetic often causes them to be heavy: their high iron content. (6, 7)Īre meteorites heavy? Typically, yes. If it isn’t magnetic, it probably isn’t a meteorite. A majority of meteorites contain a significant amount of iron. (3, 4) Question and Answer:Īre meteorites magnetic? Yes. Some would even say they are more rare than diamonds. Most meteors (90-95%) don’t survive the trip through the atmosphere, and those that do often fall unnoticed in remote areas or into oceans. Shooting stars are “small pieces of rock or dust that hit Earth's atmosphere from space” (2). Meteors are “the streaks of light we see at night as small meteoroids burns up passing through our atmosphere” (1) Meteoroids are what meteorites are called while still in space (5). Meteorites are “fragments of rock or iron from a meteoroid, asteroid, or possibly a comet that pass through a planet or moon's atmosphere and survive the impact on the surface” (1). The Campbell Geology Museum does NOT offer meteorite identification services. The most efficient thing is to send in photos if a specimen looks like it might be a meteorite, we might then ask the finder to bring it in for closer examination.Please note, this website is informational only. We are unlikely to return phone calls asking for meteorite identifications because we simply cannot identify rock specimens over the phone. If you don't hear from us, and you are eager to sell your specimen, contact one of many meteorite dealers you can find on-line.We must meet these deadlines to fulfill our primary missions of teaching and research.) (We can’t guarantee a response, since each of us has a never-ending series of deadlines related to teaching, research, and grants. E-mail 1 to 3 of your best photos to These photos will be sent out to the faculty, post-doctoral researchers, and graduate students in the hope that one of them will have the time to respond.It is hard to identify samples from photos alone, so it is crucial that the photos be sharp and with natural colors! Take a couple of well-lit (indirect natural light is best), sharply focused, high resolution photos.At Pitt, only one person in 40 years has ever brought in something that turned out to be a meteorite, and this person was a geologist. Keep in mind that you most likely do not.In particular, check out his " meteorwrongs" pages, for one of these not-meteorites is likely what you've got. Randy Korotev at Washington University in St Louis). To see if you have a meteorite, please first visit Identifying Meteorites written by meteorite expert Dr. Both iron-rich slag and iron ore can attract a magnet, which unfortunately is also a common test for meteorites. In the Pittsburgh region, most finds are either slag from old blast furnaces, pieces of iron ore, or other artifacts of the regional metals industry. Nearly 100% of all finds brought in by the public turn out to not be meteorites.
