Which Is The Coolest Planet In Our Solar System?

I think it should be Neptune (logically)

But I am sure that the temp you have provided is of Pluto who today is not a PLANET

Hope it Helps!!!

I suppose it would be neptune. (Judging by those who say that pluto is not longer a part of the planetary system).

I think it's Pluto

Neptune is the coolest planet

Pluto is coldest planet

I think that now PLUTO  is not a member of the solar system .
So the answer 'll be neptune.

The furthest planet from the sun would be the coolest. Depending on what you believe or been told or whatever. Pluto is it if your situation deems it as a planet. If not then the answer would be neptune

Pluto must be the answer if its still counted as planet (which I guess not)
 
so even I'll go for neptune after pluto!!!!

I am doing a science project and I don't know what to do it on could someone help me...please?!!?!?!?!?!

Pluto

Pluto or neptune

I'd say Earth!
