Break off a small chunk and see if stays lit (becomes an ember)

You might want to take it to a local geologist or rock shop and see what they think.

Maybe it's not for this planet?

Possibly a meteorite?

Aren't meteors supposed to be attracted to magnets?

 

[0121stockpicker]

Yes, most meteors are iron so they are magnetic. Need more info - is it metal or rock? If metal - is it magnetic or not? Etc. is it light or heavy?

Could it be volcanic rock?
