is this a meteorite?

[finderskeepers]

I found this rock/meteorite on the roof of my house a couple of days ago.
If it is a meteorite, does it seem ordinary or rare?

Here are the photos:

Any comments would be appreciated.

Is it magnetic? I’ve heard you can collect micrometeorites from your rain gutters using a magnet, so I’d assume a larger specimen also would be.

At first glance, no.

I was going to do this myself, but the wiki article says it well:

Meteorites have traditionally been divided into three broad categories: stony meteorites are rocks, mainly composed of silicate minerals; iron meteorites are largely composed of metallic iron-nickel; and, stony-iron meteorites contain large amounts of both metallic and rocky material. Modern classification schemes divide meteorites into groups according to their structure, chemical and isotopic composition and mineralogy.

I don’t have a magnet with me now but I’ll get the magnet test done soon.

One strange thing though, there’s a shadowy region on the lower right corner in both the photos - it’s not my thumb in the way of the lens, and it does not appear while taking photos of other objects - it’s there in every one of the photos I’ve taken of this rock (and from different angles as well).

When a meteor enters the Earth’s atmosphere the resulting fireball produces light, due to the friction between its surface and the air.

Uh, no. Read “When a meteoroid enters … fireball, called a meteor, …”

Update:

@Colophon:
It is not magnetic.

It is heavier than one would expect of a rock of that size.

Looks like it could be a pyrite nodule - those are typically heavier than they look, and often have a rusty appearance.

If the flash you used is on the camera body it’s likely to be the lens casting a shadow.
