Title: Far out planets...
Post by: Randy on October 18, 2007, 11:10:55 PM

What is a reasonable max distance out for a planet from a star?

I just found one that seems a little extreme. Its an estimated 5,500 days (1 way) at 5000 km/s

 Actual distance is listed as "2.25t". Turning on the "10x Pluto" orbit gives a circle about half an "o" distance from the star - with the planet at the edge of the screen, star in centre...

I think it might be outta reach of my first gen ships (top speed around 1200km/s - about 60 years 1 way)

Here is a very good depiction of the planetary objects beyond Neptune. Note Eris, which is a body 27% more massive than Pluto and 2.5x further from the Sun (although on this picture its semi-major axis of 67 AU is shown, not its current distance of 97 AU). I wonder what else we will eventually discover out there.
