Units in Eve - AU vs Light-year

Asked by [ Editor ]

I've noticed that besides metric units and AU's there is another unit used to measure distance in Eve - lightyear. So far I know it's related to use of jump capable ships but I don't how much distance is that; for example how many systems can you reach within 1 ly range?

Light year is the measure of distance between systems.

It is useful in Two circumstances, both when using non gate means of travel.

  1. Jump Drive capable ships

  2. Bridging ships via (Soverinty Jump bridges, Titans or Black Ops)

Each system has a map position and the grid has spatial properties. It is possible if you look at the map in 3D mode to guage distances.

Best way to tell exact distances is to use a database tool like Dotlan's Jump Planner or EVEHQ's Map tool.

Seem to remember somewhere that the average adjacent solar system is approximately 2.3 l/y apart. Don't know if that's correct or not but there we are.

In all cases the distance in Light years is a function of Racial Isotope consumed by the jump bridge/drive etc. The other factors are Ship mass for Bridges (and ship type as genearlisation for Jump capable ships), and Jump fuel Conservation skill level.

EDIT: and due to being in a meeting and slow to type, Serker has pretty much beaten me too it. +1 him.

As pointed out, Light years also effects the remote sensing for PI, although I always suspect that it operates more like supply chain management than pure light years sphere of influence... it does state categorically however distance is in Light years.

Too True, will amend my post

The PI skill Remote Sensing also is affected by LY (higher skill = further scanning).

So, AU units (~149 mil km) are used for distances within solar systems and ly units are used for measuring distances between different solar systems (1 ly = 63.24 AU)?

Having used remote sensing it is in Light years not jumps…..so it does not work like supply chain management.

Your question is answered, but nobody gave you the science or distance behind a lightyear.

So, 1m is one meter, 1km is one kilometer or 1000 meters. That, you probably already know.

1AU is one astronomical unit and means the distance between the sun and Earth. It is roughly 150 million kilometers (149,597,870.7 km).

1ly is 1 lightyear and is the distance that light will travel (in a vacuum) in one year. It is roughly 9.5 trillion kilometers (9,460,730,472,580.8 km), or 63,241.1 AU.

We like the maths :–) Well I do in any case +1

Thanks Darina, Maths is king and only avoided maths as I thought it was not the information requested. Another way of working this out if your interested is it takes on average 8mins 15seconds for light to reach the earth from the sun, light speed is 3x10^5kms^-1 (8.2560) = 148,500,000km… Likewise, (6060**24365)/495 = 63,709 AU! not bad if you prefer working with time rahter than distances.

Once you get into ship which have jumpdrive, you will see distance you can cover with your jump on the star map, much like your tactical overlay in space. Distance between stars tend to vary, as you can see on the star map, so exact distance you may travel varies too. There are only two ways to see it - put yourself into right ship and right system and see, what will get into your jump range, or use a special tool for this. Dotlan have one, for example. And I can say that 1 ly is very close, there is not too many systems within this distance of each other.
