Large-scale pic shows nice circular orbits, but the
small-scale pic shows the asteroid's orbit being bent rather
severely.

Might not be so neat next time around.

This "bend", as you call it, indicates it is hyperbolic, and that
means it won't be back, it's energy is too high to be in orbit,
i.e., it has the wrong eccentricity.

Isn't it still in Solar "orbit". That bend simply means it's in
a different solar orbit now. We don't know enough about its
orbit from that picture to know which side of parabolic it's on.

If it was in solar orbit to begin with it's still in solar orbit.
That "bend" caused the object to lose some energy.

It must depend on whether it passed in front or in back of the
earth's orbit. If behind, the earth's orbital velocity must be
slowed slightly in expending energy to create the bend, which
would be energy imparted to the object. Its new more energetic
orbit may still be a solar orbit, but will we ever see it again?

Actually that depends. NASA has gotten good at using the Earth and
other planets as slingshots to fling vehicles into deep space.

It looked to me that it came from "behind", thus the Earth would
have added energy to the asteroid's orbit. It's hard to tell
which way is "up" though. If we're looking at the picture from
above (north) the solar-system "junk" should be going counter-
clockwise, no? That would lead me to believe it did come from
behind, thus added energy.

Not necessarily, depends which way it bent! If it bent toward up-orbit,
then it accelerated and may be past solar escape velocity, only 1.414
the earth's orbital velocity at that distance from the sun. This is
what it looks like.

Someday the sun will expand and fry us. I've seen a reasonable plan
for deflecting asteroids into near-miss hyperbolic passes "in front"
of Earth, so that Earth will acquire additional energy and move to a
farther-out orbit. It would take a long time, and many asteroids, but
then the Sun will expand very slowly too.

Turns out it takes vanishingly small energy to nudge the asteroids
into the tracks needed... just a lot of information.
