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.The meteorite is 3.1 by 2.6 by 0.8 inches large. It is surrounded by a gray reduction halo, in the otherwise red limestone. Oxygen was consumed when the meteorite weathered on the seafloor.Meteorite hunters, collectors, and curators and non-specialists, including children, can use this instrument as a guidance in the identification and classification of meteorites. ...

Andrzej Muszyński. 2002, Proceedings of the Estonian Academy of Sciences. Geology ...A meteorite is an object which has fallen to Earth from space. Meteors are the flashes of light ('falling stars') produced when meteorites pass through Earth's atmosphere. Other, smaller, pieces of extraterrestrial debris also cause meteors, including grains of dust from comets. While some meteorites are found immediately after their fall, many ...Fresh meteorite fusion crusts are smooth, shiny, glassy, and darker colored than the inside of the meteorite. Note the lighter colored interior on upper right where the rock has been chipped away. Photo credit: Jim Strope. A fusion crust is the most characteristic feature that distinguishes a meteorite from a plain old Earth rock.1. Fusion crust Meteorites that have fallen recently have a black, glassy or ashy crust on their surface. When a meteorite falls through the Earth's atmosphere a very thin layer on the outer surface melts. This thin crust is called a fusion crust. It is often black and looks like an eggshell coating the rock.However, most Iron Meteorites, whether found or purchased, have lost their protective magnetite crust due to weathering on our Earth and have begun to rust.Fusion crust is covering some of the surface, but not all of it. 1.
