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.
On average, Pluto is 40 times further from the sun than the Earth is. From Pluto, our sun would be 1,000 times dimmer than it is seen from Earth. The dwarf planet's surface is covered with patches of frozen methane, with a hazy atmosphere including methane gas. What the sun might look like from the surface of Pluto: From the distant dwarf planet, the sun would be 1,000 times dimmer than it is seen from Earth. The computer-generated artist's impression is based on one possible idea of what Pluto's surface is like, where the surface is covered with patches of methane.
