Three Different Types of Vesta Meteorites. The moon, Mars and Vesta are the only planetary bodies in our solar system where we can positively identify meteorites that originated from their surface. Vesta is a very large asteroid with a diameter of over 326 miles and has a gigantic impact crater at its South Pole that is so deep that it exposes the asteroid's interior. With the photos that have come from Vesta, this huge crater is now confirmed and has been identified, using a spectograph,as the source for the three types of meteorites from Vesta. NWA 2126 is a brecciated cumulate Eucrite that formed from the impact of a large asteroid that hit Vesta. This 26X25 mm slice weighs 4.9 grams and shows a mixture of the surface rocks from Vesta with white gray light and dark brown inclusions. The second meteorite type is called Howardite and comes from a deeper part of the impact crater. NWA 3117 is a 18X18 mm fragment weighing 3.4 grams with a light gray matrix color with some white and dark gray inclusions. The third type of meteorite is called a Diogenite which comes from deeper inside the huge impact crater. This slice of NWA 2795 is 25 X 18 mm weighing 4.6 grams showing several different colored inclusions in a light gray matrix. In a 8X6 inch Riker mount. Estimated Value $500 - 800
