Consumer technology outlet CNET tweeted out a picture of the asteroid 16 Psyche over the weekend, calling it the most valuable object in the solar system. That’s because it is mostly metal, leading some to wonder how much gold can be found in “them thar space-hills”.
The tweet repeated an oft-reported value for Psyche of $700 quintillion. For those keeping score, quintillion comes after quadrillion, which comes after trillion. A quintillion is a million times a trillion. Seven hundred quintillion has a 7 followed by 20 zeros.
