Default Subsector Showing Earth

Has anyone created a subsector showing earth? Or a subsector based on the SyFy show "Killjoys"?

The Solomani Rim has Earth in it. I don't know if that's what you're looking for, though.

Could always go here: https://travellermap.com/?x=14.289&y...&options=58363

And the MTU thread has a near Earth subsector as well, I think with something closer to the stars around Earth.

Thanks for all the input. Another question, I see sector maps, subsector maps, but no blank maps for a system. What scale would a system map be based on?

System maps are almost never to scale. Too much voidness going on.

Due to the way that traveller jump drives work, the system beyond the 100 diameter limit is basically as distant as the next system, so most systems are basically undeveloped outside of the mainworld and maybe the gas giant and the odd belter in the asteroids.

Why do to Venus if you can get to alpha centuari for the same effort?

Math doesn't support your contention. Any travel under 6 days is better.

671 Gm (gigameters= million km) is the rough distance

Supporting math
6 days 6d
24 hours per day6= 144 hr
3600 seconds per hour3600= 518400s
halved to get flip time (T)2=259200 sec
quantity squared (AT/2)T= 67,184,640,000
multiply by acceleration (AT/2)10=671,846,400,000
divide by 2 (AT/2)2= 335923200000
m per leg
double for flipping2=671,846,400,000 meters per 6 days
convert to Gm 10e9=671.8464 Gm per 6 days
convert to AU 149.598 = 4.491 AU


For the Sol System, that puts mars faster by 1G burn than by jump at all points of the year -it's semimajor is 1.524 AU, Earth's is a peak of 1.017 AU so... adding them together, peak is about 2.5 AU.

Even most of the asteroid belt is faster by 1G drive.

To recap in rounded to 1 place numbers, 6 days is:
For 0.001G 0.224 LS
For 1G, about 4.5 AU
For 2G, about 9 AU.
For 3G, about 13.5 AU
For 4G, about 18 AU
For 5G, about 22.5 AU
For 6G, about 27 AU

Adding day 7, above 1.35 (average jump duration)
Adding day 8, above 1.78 (longest normal jump duration)
Sol System orbits in AU
Mercury0.387
Venus0.723
Earth1.000
Mars1.524
Jupiter5.203
Saturn9.537
Uranus19.191
Neptune30.069
Pluto39.482
from http://www.astronomynotes.com/tables/tablesb.htm


If the source world and the target world, added together are less than the distance by thrust, it's always in reach faster by that constant thrust. If the difference (|A-B|) of the two is less than the distance by thrust, it's sometimes faster.

Not so.

A good scale for system maps is anywhere from 0.1 to 5 AU, depending upon what you're needing it for. Note that worlds are points on this scale, but that's irrelevant for mapping purposes; if the locus of worlds on jump charts was to scale, you'd not see the stars, let alone the worlds around them.

Noting that earth's orbit travel is about 6.3 AU, if your system turn is a day,
you need 365.24 hexes for an orbit, which, if "simplifying" orbits to hexagons, is 0.017 AU per hex... and radius 58 hexes. Doable.
Make it a week, 52.17 turns per year, so, earth hits radius 9... and each hex is about 0.12 AU.

That's just one orbital path. Who would bother with mapping the 7 other orbital paths on the same map? That's why I mentioned scale.
