The map of the inner system of the Talosian system depicted the distance from the binary stars on a line. At every 10 intervals, there was a mark which represented one astronomical unit. The map showed that the inner system reached 3.4 astronomical units. 



The intense energy cloud created by V'Ger was approximately 2 AU in diameter. 

The nucleogenic cloud being measured 7 AU in diameter. 

When searching for Harry Kim in 2371, the USS Voyager performed a subspace scan with a scan radius of 10 AU.
