Star wathing with telescope,and noticed star not moving with earth rotation,looked at and it looked like a dusty star with high peeks on it,rotating fast,stationary for about 10 min.,then took off.

Late at night,wanting to do some star wathcing,since there are littel lights in green bay/minamonee wisconson,so me and my dad went out to look at some stars with my telescope (small 450 power),looking around at the stars I noticed a star not moving with the earths rotation,so I turned on object with telescope and it looked like a small dust covered moon with high peeks,like spikes,rotating faily fast,in one spot,I could not believe what I was seeing,and I asked my dad to look at it,so he did,and I asked him what are we going to do,he seen it to,and he said I dont know,then it took off and left area.
