Abstract
A meteorite is a fragment of iron, stone or stony–iron rock. The falling of meteorites to Earth's surface is part of Earth’s accretion process from dust and rocks in our solar system. When these fragments come close enough to the Earth to be attracted by its gravity, they may fall into the Earth. Following the detection of objects that fall from the sky onto a home in Phitsanulok on June 27, the meteorites were analyzed by Scanning Electron Microscope (SEM) and X-Ray Diffraction (XRD) instruments. XRD analysis shows presence of three main elements in the meteorites, which are Forsterite, Enstatite and Anorthite. The data from SEM analysis shows that the meteorites are mainly composed of Fe-Ni and Fe-s. The meteorite is Achondrite, a class of meteorite which does not contain Chondrule. The meteorites in this work are thought to be part of a large asteroid.
