Representative samples of meteorites namely, 1) Sikhote Alin (iron meteorite), 2) Campo-del Cielo (iron meteorite), 3) Nantan (stony iron meteorite), 4) Morocco (stony iron), and 5) North West African meteorite (likely to be of chondrite in nature), were investigated to understand their source and origin with respect to their physical properties and chemical compositions. XRF Analysis carried out showed that 1) Sikhote Alin contains Fe - 89.0%, Ni - 4.83% and Si - 3.51% with other elements in minor compositions, 2) Campo-del Cielo contains Fe - 97.4%, Ni - 1.15% with other elements in minor compositions., 3) Nantan contains Fe₂O₃ - 66.8%, SiO₂ - 22.7%, Aluminum - 6.380%, Nickel - 1.760% with other oxides in minor compositions 4) Morocco meteorite contains Fe₂O₃ - 45.7%, SiO₂ - 17.2%, CaO – 14.2%, MgO – 10.9%, SO₃ - 3.80%, Al₂O₃ and NiO – 2.42% and 5) North West African meteorite (N.W.A.) contains SiO₂ - 39.9%, Fe₂O₃ - 27.4%, MgO – 20.8%, Al₂O₃ - 6.040%, CaO – 2.34%, SO₃ - 1.610% and NiO – 0.734%, with other oxides in minor compositions Objects fallen on earth so far has been given a common name ‘meteorites’ The authors of this paper broadly classified meteorites into ‘Seteorites’ and ‘Uniteorites’. The source of ‘seteorites’ is from our solar system and the source of ‘uniteorites’ is from beyond our solar system. Physico - chemical nature of ‘seteorites’ and ‘uniteorites’ are different as per their source. This paper aims at carrying out a detailed study on seteorites (meteorites), to understand their source, origin and their distribution in the solar system with respect to their physical properties and chemical compositions on preliminary basis.
