how do i net the wandering star?

easy: increase my gravitational pull until she's trapped in my orbit.

or will she do that to me, creating a binary system that wanders endlessly through the universe?

or maybe i've thought about this so long that i've misread the situation. that's been known to happen ;)

no, actually, sadly, it hasn't. my cutting intuition seems rarely to be wrong, as long as i'm honest.
