What do I have here? My dad thought it was a meteorite

Mon Jan 13, 2014 9:35 pm

My dad says he found this in his front yard one day in a small crater. it doesn't appear to be magnetic, a magnet won't stick to it. Figured I'd see if there are some people out there who could help us identify it.

Nobody knows, eh?

Since it is not magnetic and it has what appears to be oxidation, it is probably not a meteorite. Generally a meteorite will have smooth pitting as the outside of the material is ablated by the heat. You also will not have any oxidation, unless the sample has been sitting for a long time. It should be very smooth with no sharp edges, except where the pits terminate up against each other.

Honestly, it looks a bit like a hematite or limonite nodule, which could make sense if someone dug a hole (small crater...) and found the concretion. I am leaning toward hematite. You can see a short description here (if it doesn't let me link you can search google for meteorite identification hematite):

If you don't believe that is what you have, you can answer the questions below and we might be able to narrow it down a bit more.

First, how dense is it? A relative example of something about the same size would be fine, like density of a pool ball or about as heavy as 5lb sledge.

Next, what area was the sample found in? What is the soil / rock on the surface? Are major roads nearby? Do you have any other rock around? Has anyone done any landscaping recently?

Also, can you scratch it with a fingernail? A penny? Can you scratch glass with it?

After we know those things we can start to narrow it down a bit.
