If it had to be more of a location I'd say somewhere in the oort cloud....

What does SS sand for BTW?

I read that the night side of Mercury is one of the coldest. Also the bottom of those polar lunar craters that are in permanent darkness. Other than that, the Oort cloud seems like a rather obvious choice.

Mercury has the most extreme temperature range of the planets but Neptunes largest moon Triton is the coldest I think, at around 38K
..though i'm sure Pluto could give it a run for its money 8)

I won't bother to ask a (non-observational, non-SS) question since c-m has one pending.
Thank you Tobin Dax...Mizar A &amp; B and Alcor, in the handle of the Big Dipper. I like binary stars. :P

Tobin Dax is up to ask a question....

A question is asked. Someone gives an answer and then they ask the next question. We don't wait for the answer to be confirmed as correct because that gets to be a problem.

Example Question: What is the brightest star in the sky?
So if I say
Ganymede

and I ask

What is the planet that revolves backwards?


What happens now?

Do we just say:
Try again?(LMC?) or what?

I suppose that would be a problem though....

Just carry on I guess. If we wait for the correct answer to be given and confirmed, then it would really slow things down.

Yes, but I was asking about the hottest place in our solar system, excluding the Sun? There is a hotter place yet (and it is not too weird an answer).

I suppose the cauldron of any steel mill would be hotter. IIRC, the particles in a CME are far hotter. Then there is the day side of Mercury.

My question, for the folks who don't have many letters after their name (that be me too), is : which moon in the solar system is the most massive, proportional to the planet it's orbiting?

Those would be trick answers but it's not a trick question. It's an orbital body (this should give it away).

Nope.

Well, there is Jupiter's core. Jupiter is an orbital body.

But I'm guessing you were thinking of the volcanoes of Io.

OT: Thanks for the award, Melusine.

Yup, you're right Roy. 8) Triton is the coldest recorded temperature, seeing how there's no way to even guess the temperature of an oort cloud object.

So I guess it's time to ask another question?

I'll go another easy one....see if we can get more interest in this topic. :P

Which planet has the most moons?

with regards
