3.26 light years equals 3.08413226 × 10^13 kilometers.
Almost 28 years
440 light years = 2.58653992 × 1015 miles
3 light years is equivalent to about 28 trillion kilometers. It takes light 1 year to travel a distance of 1 light year.

The longest galaxy known is the "Great Wall," which is a filament of galaxies stretching over 500 million light-years across. It is a vast cosmic structure made up of galaxy clusters, superclusters, and voids.
space means a outside cold world lightyears and lightyears away in the deep space
It would all depend on the speed travelling, as time = distance/speed.
The closest (DX Cnc) is 11.8 lightyears away. The farthest is nearly 4000 lightyears away.
The Crux or Southern Cross constellation is made up of four stars which can be joined in such a way, by an observer on earth, to make a cross shape. Although the smallest constellation, it is one of the most distinctive, appearing on both the New Zealand and Australian national flag. In the sky, it is not very long, maybe just as long as the width of the thumb at arms length. In real terms the distance between the top of the cross (a star called Gacrus) and the bottom of the star (Acrux) is huge. Gacrus is 88 lightyears from earth, while Acrux in over 320 lightyears from us, so a distance of about 230 lightyears separates them. The other two main stars in the constellation are around the same distance as Acrux, 353 and 364 lightyears.
