Your Sun is Losing Weight

Really. The Sun is the fatso of our solar system representing 99.8% of the mass, but it's losing 5 million tons every second!

The Earth from our vantage point seems pretty darn heavy, but it's puny by comparison to other planets such as Saturn and Jupiter. Indeed all the planets are only two cents out of ten dollars when it comes to mass.


Think of it this way, if you were the Sun your undershorts would weigh more than all the planets combined.

The Sun is mostly hydrogen that's slowly being converted into helium by nuclear fusion..."slowly" meaning that 700 million tons of hydrogen are converted into 695 million tons of helium every second. The "lost" 5 million tons is converted to pure energy as described by E=mc2.

If you'd like to know more about Mr. Sun ("You can call me Sol," he says) he was interviewed back in 1987. You find the transcript here.
