One Void Unit is Approx. 10,000 Kilometers:
so 3 VU= earth diameter, earth to moon = 38 VU; earth to Venus = 4,200 VU,
earth to closest asteroid, 2,950 VU, earth to Mars = 10,000 VU, and 1 A.U. = 14,960 VU
Detection Range is 20 VU + 5 per DoS of scanner, on Active Augury. Distances can go much farther for such items as:
Weapons Fire, Flaring Engines, Energetic Phenomena, Huge Objects, Planets, Active Scanners, etc....
Silent Running:
Ship is half speed, maneuvers at +10 penalty, and all ship board skills are - 1 DoS.
Some failed skills checks, especially helm, blow the silence and reveal your ship.
Ship becomes largely undetectable outside of the range above, unless detector has psychics, xeno tech, etc.
The Mandeville Point, or "closest safe warp translation distance" varies widely and depends on many conditions.
