“Don’t go around saying the world owes you a living. The world owes you nothing. It was here first.” -Mark Twain
So, you’ve been around a while, seen all sorts of things, and learned an awful lot about the world, solar system and Universe that we live in. But how well do you know it, really?
To scale and in order, these are the eight planets you know so well. There are the four rocky worlds of our inner solar system: Mercury, Venus, Earth, and Mars, and the four gas giants that dominate the outer solar system: Jupiter, Saturn, Uranus, and Neptune. With our huge assortment of terrestrial and space telescopes, as well as interplanetary space probes such as Cassini, Messenger, the Mars missions and, of course, Voyager, we’ve taken some amazing images of every one of these worlds.
My question for you, however, is can you recognize them? A long time ago, I made a quiz to see whether you could tell Mars from Arizona in pictures, and it was difficult even for Arizonans to get them all right. Let’s see if you can solve the mystery of which image is of which planet?
Below, I’ve got for you eight images in random order, one each of a portion of each of the eight planets. The images are all in true color, where available, or altered to be as close to true color as I can make them. Let’s get right to it, and see what you can come up with!
What have you got? Leave a comment and let me know if you’ve figured it out, and bonus points if you can identify where on each planet the image was taken!
For those of you that need a hint, I’ll tell you what the origin of the seven non-terrestrial pictures were: two are from NASA’s Voyager spacecrafts, two are from NASA’s Cassini spacecraft, one is from NASA’s Mars Opportunity Rover, one is from NASA’s Magellan spacecraft, and one is from the NASA Messenger mission. Three of these — Cassini, Opportunity and Messenger — are still ongoing, for what it’s worth.
Can you solve the mystery?
