Unfortunately, I can't find a more recent update, but it's possible that
P6
is the oldest working object in solar orbit.

Jupiter's doing OK for 5 billion :-)

Of these, how many are RTG powered?

None, Pioneers 6-9 and E had solar cells. That page says so, in fact.

Working? Dunno. Bit of a couch potato I'd say - I mean, look at its waist
size. And if you want even older, best candidate would probably be a KBO of
some sort...

No, Jupiter worked for the first few million years and has been goofing
off ever since. :-)

None. Only the outer-planets Pioneers (10 and 11) used RTGs. Solar power
is generally preferable in the inner solar system, except possibly on
planetary surfaces.

I think a few years would be great, just keep rovin, rovin, rovin, snap up
lots of great panoramas!

And don't forget more 3D picture, when I got in my anaglyph stereo
glasses today. There have been a few 3D pictures so far, but when they
get to some unflat landscape, then I hope that there will be a lot
more.

Here is one for example...

If anyone needs some suitable 3D glasses, then take a look on EBay.

And the General Electric AM/FM/TV mono radio playing talk radio as
type has been working (part time) for about 36 years. (I've got
another working Made In USA stereo radio that's almost as old, while
many newer Made Elsewhere electronics have gone belly up after a few
months to a few years. Oh well, the new stuff works better and is a
lot cheaper.)
