Alright, if anyone wants to edit there save file to move the Asteroid the correct amount of away they need I have found out how:
Scott Manley's video helps explain the basics of how to edit saves: https://www.youtube.com/watch?v=0wXVm3M2I2w
1. Record the amount of mass the Asteroid you want to move has, mine has 97.97623t (you only need the first 5 numbers aka: 97.976) this is so you can find the right part to edit later.
2. find your save file and open it in notepad. the file can be found at: C:\Program Files (x86)\Steam\steamapps\common\Kerbal Space Program\saves\(career_name)\quicksave.sfs
3. press Ctrl+f and search the mass you recorded earlier, you should see a part listed as "name = PotatoRoid, position = -0.033608634024858475,12.991914749145508,0.046582106500864029" etc. This is the part you want to fix.
4. Edit the position, rotation etc. to move the Asteroid away from the ship (it will still be a "part" of the ship, but it will no longer be clipping if moved far enough away) I just added 20 to the numbers: position = 20.033608634024858475,12.99...
5. you should be able to disconnect the claw, or play with the position numbers to fine tune it's position.
Good to the small amount of people who might chance ujpon this glitch.
