This poster is based on the high-resolution original of Comic #681. It shows the depths1 of various gravity wells in the solar system. The poster version has some additional diagrams showing the scale of the gravity wells of the solar system, Milky Way, and Great Attractor. It is about 35"x15".
1(The depth of the well corresponds to the energy it would take to escape the from the planet; it is the height you would have to climb upward in constant Earth surface gravity to spend the same amount of energy as it would take to escape the given planet completely.)
