Titan Has Enough Propane For 23 Million Trips Around the Earth
New findings from the Cassini mission to Titan — Saturn’s largest moon — show that its atmosphere contains about 29 billion gallons of propane.
Given that the average new car fuel economy in the US is currently about 20 miles per gallon, and that propane-converted cars get about the same mileage as regular gas cars, there’s enough propane on Titan to take one average car more than 23 million times around the Earth’s equator.
Wow! So what you say? Even though that may sound staggering, you still aren’t convinced that it really means anything to you? What if I told you this: that’s only enough propane to satisfy the propane needs of the US for 18 months.
