One price quote puts the diameter of the known universe at 28 billion light-years in diameter.Why usage light-years? Starting in our cosmic area, the closest star-forming region to us, the Orion Nebula, is a brief 7,861,000,000,000,000 miles away, or revealed in light-years, 1,300 light-years away. The galaxy GN-z11 is believed to be the farthest detectable galaxy from Earth at 13.4 billion light-years away.Like degrees, the light-year can likewise be broken down into smaller sized units of light-minutes, light-hours or light-seconds.
