Asteroid classes in tracking station

[Durf]

So I got my first real asteroid mission; put a class A asteroid in orbit of minmus. I have about 100 asteroids currently being tracked, both from the tracking station and from a Sentinel so i thought i could just pick a nearby one and go after it.

The problem is that I dont know how to tell what 'class' they are from the tracking station. I have done some googling to try and find an answer but no-one else seems to have the same problem, which makes me think I'm just being an idiot.

If some kind soul could point me in the right direction it would be most appreciated.

Here's a picture.  That's in the tracking station; you find it with the 'Object Info' button.

Here's some more information about it.

Ah, as I suspected, I am an idiot.

Thankyou
