Hello,
after investigation I see that you set your ship accidentally to public. This means everyone can access the ship.
So as you can see someone else is flying it currently.
In such cases not much we can do since that is a normal game mechanic and public means public - especially in PvP space. At least I could warp you back to starter planet in this case.
You might also ask the new owner if he refunds some stuff.
