This rock contains, what NASA believes is, fossilized Martian microbial life. Meteors move very fast. That is far over 50,000 mph meaning up to 110,000 mph. Meteorites and other space debris, contribute about 27 million tons of matter to our planet every day, most of which is in the atmosphere. They're constantly falling.
Meteorites come in three forms such as stony, stony-iron and iron based.
The way to know if you found a meteor is if it is heavier than an average rock of its size and if a magnet or something magnetic sticks to it. Another way is by cutting it with a special saw. After cutting it, if it shows interesting intersecting lines with a kind of glistening whitish-silver you have a meteorite. The larger the meteorite is, the more it's worth. Thirteen of us, mostly students, drove to observe and record the Leonids atop Kitt Peak on the night of Nov. 16-17, 1966.
