Meteorites
• Meteoroids– “small” rocks orbiting in space
• Meteors– “rocks” entering the atmosphere and glowing– Most are the size of a grain of sand– Some are a lot bigger!!!
• Meteorites– Rocks from space that have hit the Earth

How do we know they are from Mars / the Moon / 4 Vesta??
• Mars: Viking 1 and 2 had soil and atmosphere analyzers. The percentages of the elements and isotopes are the same as the SNC meteorites – and different from others!
• The Moon: Same story – except we have real moon rocks to compare them to
• Vesta: Spectroscopy of Vesta indicates it is made of HED materials, and no other asteroid is. Recent studies show a great crater on Vesta where some of these materials must have been ejected from.

How to Study Meteorites
• What does it look like (big picture)
• What does it look like (microscope)
• What elements are in it (chemistry and microprobe)
• What isotopic ratios are there (microprobe)
• Where did it come from (compare to asteroids and planets)
• How did it fall (distribution)

Meteorites / Meteorwrongs
• Meteorites are not hot when they hit the earth!• Almost all meteorites are magnetic!• Almost all meteorites have some visible metal
(though sometimes only a little).• Most meteorites are denser than local rocks.• Meteorites don’t have holes/bubbles in them.• For real analysis you have to take it to an expert
![Page 32: Meteorites Fragments of the Solar System. Dedicated to Dr. Elbert King –First director of the Lunar Receiving Lab –Recovered a lot of Allende!! –Meteoriticist.](https://reader030.fdocuments.net/reader030/viewer/2022013003/55156acf55034685568b5ec7/html5/thumbnails/32.jpg)
How to Study Meteorites
• Thin Sections – The coolest way to look at meteorites is in “thin section”. Take a thin slice of the rock, glue it to a microscope slide and grind/polish it until it is 30 micrometers thick. You can then look at it under a “petrographic microscope” with crossed polarizing filters. The colors tell you the minerals!
