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.
It varies hugely. Pluto follows the most eccentric orbit of all the planets. The closest Pluto gets to the sun (Perihelion) is 4,437,000,000 km while the furthest it gets from the sun (aphelion) is 7,311,000,000 km. Earths orbit is much more circular with a perihelion of 147,095,000 km and an aphelion of 151,930,000 km. For distance between Pluto and Earth :-.
