We’ve reached Neptune, the final planet in <a href="http://www.astronomycast.com/category/solar-system/">our tour</a> through the solar system – but don’t worry! The tour’s not over, but after this week we’ll be all out of planets. Neptune has a controversial story about its discovery, some of the strongest winds in the solar system and some weird moons.

I just listened to the Neptune episode and thought I'd answer a question posed: If Triton forms a ring system, it will be much more massive than Saturn's. Saturn's ring system is estimated to be on the order of a few times the mass of its moon Mimas, which is made of 3.8x10^19 kg of material. Triton, on the other hand, is nearly 1000 times more massive at 2.14x10^22 kg.
