The Sun is mindbogglingly massive in comparison to the rest of the solar system. Just how massive?
The least abundant isotope detected in the Sun is Uranium-235, which accounts for 0.000 000 000 000 002 067% of all its atoms.
However, due to the sheer size of the Sun, there's approximately 1.075 QUINTILLION kilograms of U-235. Or, put another way, a little under 79.7% of the mass of the Earth's oceans.
