I like this. It really helps illustrate that how long it takes to get to Mars can vary hugely depending on when you leave Earth.

My kids learned in school (during the 5 minutes of the year they spent talking about the solar system) that Venus is closer to Earth than Mars, but I had to use a diagram like this to explain that that's only sometimes true

kind of limiting that you can only go back and forward in time one month though. I would love a slider, a play button
