Copper burns green, but I have never heard of copper meteorites.
The bright green color of some meteorites is caused by the internal combustion of metals as they pass through the upper atmosphere. Many asteroids are rich in nickel and have trace amounts of copper. Both metals burn green when sufficiently heated.
