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.
Take a look at the Solar System from above, and you can see that the planets make nice circular orbits around the Sun. But dwarf planetâs Plutoâs orbit is very different. Itâs highly elliptical, traveling around the Sun in a squashed circle. And Plutoâs orbit is highly inclined, traveling at an angle of 17-degrees.nstead, Pluto orbits at an angle of 17-degrees. For part of its orbit, Pluto is above the plane of the ecliptic (where the other planets orbit) and other times itâs below that plane. Because the orbit of Pluto varies so widely, it can switch places with Neptune, orbiting closer to the Sun.
