I'm now 162,461 AU or 24,303,882,000,000 kilometers away from the sun and moving at the speed of 1,027,122 kilometers per second!
You have to be heading toward some constellation whether you want to or not.
Constellations are directions, not locations.
Here is how to find out:
Hit F9 to bring up the planetarium.
Then press F4. Press "visual helpers" button. Then under the "planetarium" tab check "lines" and "labels"in the "constellatons" section.
Now go to your HUD in orbit view. You should be able to see what constellation your prograde marker is in.
So, are you saying that you can pass the speed of light in orbiter? :nono: I dunno.... so, light speeds are only Einstein physics?
