Meteor showers are usually named after a star or constellation that is close to where the meteors appear to originate in the sky. Perhaps the most famous are the Perseids, which peak around August 12 every year. Every Perseid meteor is a tiny piece of the comet Swift-Tuttle, which swings by the Sun every 135 years.

Meteorites as we have learned so far are rocks from outerspace that come from asteroids or planets. So how can we tell for sure we have found a meteorite? Not all meteorites will have all of the following characteristics, in fact most will have 2 or 3 but that should be enough to have them tested further when we get home.

Weathered meteorites are highly susceptible to aqueous alteration because their high-temperature and reduced mineral compositions make them chemically reactive in oxidizing environments. Moreover, while some meteorite types show signs of pre-terrestrial aqueous alteration, the majority are unaltered prior to arrival on a planetary surface.The Mars Meteorite Compendium (MMC) is an attempt to introduce these rocks to new investigators and give.
