Given how close its perihelion is to Earth's orbit, any chance this is actually an old booster? If it were > or < white, as most such boosters were, it could be considerably smaller than the estimated 4 to 8 meters.

I should have said upper stage. A year ago, J002E3 turned out to be the Saturn IVb stage from Apollo 12 in an interplanetary orbit (and temporarily re-captured by the Earth).
TBH, I wasn't thinking there would be any space junk out there, beyond Earth orbit. But it stands to reason that missions destined for places beyond Earth orbit would leave junk out there, too.
