Article#341 - Visualizing Gravity Wells

Click here to view the large version

Another great new infographic comic from xkcd.com.  A mix of real science and humor, this one plays on the words “gravity well” by visualizing the strength of each planets gravity as the depth of a crater scaled to Earth’s surface gravity.

The chart shows the “depth” of various solar system gravity wells.

Each well is scaled such that rising out of a physical well of that depth - in constant Earth surface gravity - would take the same energy as escaping that planet’s gravity in reality.
