1 Thorium fuels can breed fissile uranium-233 to be used in various kinds of nuclear reactors. 2  Molten salt reactors are well suited to thorium fuel, as normal fuel fabrication is avoided.
Since Pluto has a much higher axial tilt of roughly 119.5 degrees, it has much larger arctic and antarctic circles, each stretching from roughly 29.5 degrees latitude to their respective poles. This means that at the peak of Plutoâs summer the area receiving the most direct sunlight is actually in the arctic circle.
Yes, Pluto is closer to the Sun than Neptune for a ~20 year period every 228 years. The last time it was closer to the Sun than Neptune was 1979. This happens because Pluto ha â¦ s an eccentric orbit that is also highly inclined, Pluto's size\\mass is not directly involved in this process in any way.
