wikipedia - check the numbers

found this entry for the Sun on wikipedia:

The Sun is the star at the center of our solar system. The Earth and other matter (including other planets, asteroids, meteoroids, comets and dust) orbit the Sun, which by itself accounts for more than 99% of the solar system's mass. Energy from the Sun—in the form of sunlight, supports almost all life on Earth via photosynthesis, and, via heating from insolation—drives the Earth's climate and weather. In a single second, the sun fuses 600,000 tons of hydrogen into 596,000 tons of helium. The remainder is released as energy.

the numbers are wrong. here's nutty's edited and submitted entry to wikipedia: a single second, the sun fuses 600,000,000 tons of hydrogen into 596,000,000 tons of helium. The remainder is released as energy; that's 4 million metric tons a second! and it's been doing this for approximately 4.5 billion years - approximately halfway through the Sun's life cycle.

editing their page was really easy. the only problem i have is that anyone can write anything, so if you need to know, get hold of a real reference.
