Furthermore, when a newly fallen meteorite can be matched with the trajectory of the meteor that deposited it, this enables scientists to determine both its mineral content and what part of space it originated from. What you need are: a good magnet, several sealed plastic bags, a few larger plastic bags, markers pens, sieves with different sizes, a dissecting microscope or magnifier, and wooden sticks.5.

While most meteorites have a smooth surface with no holes, some meteorites exhibit thin flow lines or thumbprint-like features called regmaglypts. According to O. Richard Norton and Lawrence Chitwood in their book "Field Guides to Meteors and Meteorites" (Springer, 2008), many meteorites have been found in the Mojave Desert's Rosamond, Muroc and Lucerne dry lakes, among others. Within the Mojave or another desert, ancient, dry lake beds are ideal places to search, because their surfaces have likely been exposed for millennia. Some space rock hunters aren't content to simply look for long-lost meteorites. meteorites were discovered in 4.5 billion years ago on Earth.
