If you see my previous post, you'll see that 17x the mass is not the same as 17x g
Ah okay, fair enough. Still, 3x would be quite difficult to walk, if possible at all. That's like carrying another two of yourself on your shoulders. I doubt I could.
Mega-Earth found and it's 17 times Earth's mass

560 LY. Even at full tilt, the Sulaco would take 414 days to get there. I think anyway.
Max velocity 0.74LY per sidereal day.

I can do quite a few pushups. I once tried with someone lighter than me sitting on my back. I managed one pushup. It took a good 20-30 seconds to fully push up. All my joints clicked and snapped on the way up.
On this new planet it'd be like having 3 more people on me when i was doing a single pushup solo.
No thanks! haha

I still find it amazing we can estimate this planets size from such a distance away.

I once did a pushup on a set of scales to see roughly how much weight was actually being lifted given that my feet are on the floor, it was approx 60% of my bodyweight, by that rational 3G would be equal to a pushup of 180% of actual bodyweight. (extremely difficult I would imagine, I certainly couldn't do one)
Atomic is correct, however the environment ultimate size is not entirely correct (unless you're basing it all on food accessibility).
Creature composition is the most important part of this - else we'd see Beetles the size of cars etc.
Their exoskeleton loses all advantages over a set size due to weight, food requirements, ligament structure, ability to fly etc
If a creature had a more energy efficient digestive and movement system, as well as nervous systems that could handle extra 'data' and brains big enough to deal with the 'data' correctly, then you could theoretically increase any creature in size.
You'd also need to consider bones vs. exoskeleton as well as muscle fibres etc.
mavity is important, but not the limiting factor here. Evolution is.
Hmmm I wonder?
45 day year? How'd that work? Every 10 days season change. keep the fashion industry ticking over I suppose
Seasons are based on the rotation of axis, not the point at which the planet is orbiting its star.

Pity it's so far away, we really need to break the light speed barrier by many times but even then it'd only be good for traveling around our solar system. Instantaneous travel from one point to another by bending space would be the only real chance of reaching out to the stars, sending a can of worms in orbit to start digging would be a good start.

Another way would be to work out some kind of human stasis. And we have already sent a craft out of our solar system, Voyager 1 left the heliosphere last September, iirc.

I think the problem with Human stasis would be a severe lack of volunteers willing to give up their life on Earth, 8 years round trip to the nearest star at light speed would see many more years over the 8 passed on Earth, not sure how many though.
Although it would be good for a manned mission to Mars with our current speed limits, reminds me of 2010 Space odyssey where they used it for the trip to Jupiter.
Well using our current fastest form of space travel, that's only a short stint at more time that humans have existed on earth (something around 132 Billion years).
