*sigh* okay...
I didn't want to waste a lot of time on this, but you're probably looking at a GOES or some other weathersat shot of the Earth and, yes, the Moon. Flip it to negative and kill the color.
The Moon is often "ovalized" in a GOES shot.
There is no possible way any satellite could get a photo of an asteroid passing the Earth except, with immense luck, as a streak against the sky. Certainly nothing that looked like an oval rock.
