What the hell just happened?

So after getting the rank of Duke for the Empire I made my way to Summerland to check out the price of the Cutter. Upon arrival I circled the Star to refuel and honked the system. I selected the space station to make my way there. All of a sudden my FSD goes into overdrive and I’m being flung around at over 4,000c. I quickly drop out of super cruise before my ship reaches 0%. I think I was around 10% before I realized what was going on. After I realign with the space station and enter super cruise I realize it’s going to take me something like 10 minutes to even get back into the systems orbit. In total it took me 12 minutes to get to the space station. Has this ever happened to anyone before?
