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.
Astronomers call this orbit eccentric because Pluto follows an orbit that traces out an elongated ellipse around the Sun. Plutoâs orbit is also highly inclined. This means that it doesnât orbit within the same plane as the rest of the Solar System. Instead, 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.nstead, Pluto orbits at an angle of 17-degrees.
