A question mark for the star sport means I haven’t decided yet what type, if any, star port is there. Of course, certain types of technoloogical type worlds would require at least a landing area.

Since I came up with larger worlds than are in the OTU, the following is the diameter, circumference, and gravity. These are standard density ‘Earth-like’ worlds.

Planet diameter B = 8,800 miles , 27646 miles circumference is 1.1 Gs

Planet diameter C = 9,000 miles, 28274 miles circumference is 1.125 Gs ( one and one eighth Gravity)

Planet diameter D = 11141 miles, 35000 miles circumference is 1.39 Gs

Planet diameter E = 11459 miles, 36000 miles in circumference is 1.43 Gs

Planet diameter F = 12,000 miles, 37699 miles circumference is 1.5Gs

Planet diameter G = 50,000 miles, 50000 miles circumference is 1.99 Gs

Planet diameter H = 4222 miles, 13263 miles circumference is 0.375 Gs

Not all of the galaxy has enough gas clouds to use this form of transport.

Dense gas concentraton: speed is up to three parsecs a week.

Medium gas concentraton: speed is up to two parsecs a week.

Light gas concentraton: use another means of transport

Beware ! As some of these ships advertise themselves as holiday excursions to many star systems, or a good all around means of transporting large numbers of people. These are actually generation ships built to look like Bussard RamJet ships and move no more than 1 light year per century ! Tau Zero effects do take place, but not in the early parts of the voyage, i.e. several centuries after leaving a solar system.

Travel more than 300 parsecs, and learn that what is common one place, isn’t so common another place.
