No. It is hydrogen fusing to helium. It should have a small amount, just as there is on Earth, of the more stable isotope Plutonium-244 with a half life of 80 million years, which must have been created in supernovae, and was present in the nebula that condensed to form our solar system. read more
At the core of the Sun, plutonium whether it is manufactured by the Sun or dropped in by a visitor will not survive long. It will all fission quickly. As such Sun is both an efficient fusion and fission reactor. read more
The sun has no Plutonium. The sun is powered by fusion. Fusion stops at iron. Plutonium is far heavier than iron So it cannot be used for a fusion reactor. Plutonium is only used in fission reactors (the opposite type of reactor). read more
B) Astronomers create mathematical models that use the laws of physics, the Sun's observed composition and mass, and computers to predict internal conditions. C) We have sent probes below the surface of the Sun. read more
Enough of the right Plutonium isotope might make Saturn radiate like a star, but not for a long time. Plutonium 238 has a half-life of 87.7 years. Other isotopes half-lives of Pu 239 = 24,100 yrs, Pu240 = 6560 yrs, Pu241=14.4 yrs, and Pu242=376,000 yrs. When Plutonium decays it releases energy - in the case of Pu 239, it is about 500 Watts per Kg. read more
A) Higher temperature would cause the rate of nuclear fusion to rise, which would increase the internal pressure, causing the core to expand and turn the Sun into a giant star. read more
