Origin of the Earth

Every time I hear, "The earth formed X.X billion years ago," I subconsciously compare it to the number I learned back in 9th grade science, 4.6. I'm always expecting it to grow larger due to the time lapse between 9th grade and now. But of course it hasn't changed, because that was only 0.000000012 billion years ago, and therefore not significantly different.
