Svivren I's heat may seem dangerous but it is nothing in comparision to the entirely gaseous lead atmosphere. With temperatures well about 10000 degrees, this planet is so hot it does not seem to have a liquid or metal core, rather a gaseous core formed when the sun was nothing but a small dwarf star... and the planet was no where near as hot. Since the the nearby suns increased temperature has caused the core to melt, however the gas that remained still held together. Another danger of this planet is that it is radioactive. Possibly, this might be another reason the planet's heat shot up rapidly 1000 years ago, destroying all life within a matter of two days. Also this planet is known to be so hot that it warms up other neighbouring planets 1-2 degrees.
