where to now?
from here - there is no place to go -
Mars is too small - even if Solar warming got it to a reasonable temperature, it cant hold a decent atmosphere.
Jupiter... too big, too much gravity. Too much stuff (atmosphere) as well.
One of the moons? maybe - but they are all small too, same problem as Mars, cant hold an atmosphere.
Titan? - it would be the next & last step, in this solar system. However, it is so far out, that Solar warming, and Saturian reflection would not be enough heat. At least not until Sol becomes a red giant - something like 1.5 billion years. I fear it will be a little too late by then.
The only other option would be vary hard. Build a planet. There is the rubble in the astroid belt. Mars, Luna, Phobos, and Deimos. Combined, there might be enough mass to hold decent atmosphere.
But my first observation on this idea is : We cant even plug a leak in an oil well......
So... save this one, or give up.
as National Lampoon so nicely put it :
With all its hopes, Dreams, promises, and urban renewal,
The World continues to deteriorate.
Give up !
You are a Fluke of the universe...
You have no right to be here...
Whether you can hear it or not,
the universe is laughing behind your back...
Pirates because - if we move, we'll have to watch out for Space Pirates :)
