Welcome, fellow space traveler!
Here is your mission:
1. Find something extraterrestrial that is named after something or someone on earth and submit proof of that object (website, etc.).
2. Find the equivalent on earth, take a picture of it and submit the coordinates.
The extraterrestrial object can be anything from the little Martian rock named Scooby-Doo to an entire celestial object, like Halley's Comet.
The equivalent object on Earth must be something that can be pinpointed to a specific location like the statue of a person or a mountain top. In case of entire mountain ranges, it should be something local carrying the name. So, for the Lunar Alps, for example, one couldn't just log any location in Switzerland or Austria, but the visitors center of the Alps National Park would be acceptable.
Here are some examples:
Mount Olympus on Mars and its namesake, Mount Olympus in Greece.
The Christa Mc Auliffe Crater on Venus and her name on the Challenger Memorial in Columbus, Ohio.
The Tsiolkovsky Cater on the moon and the Tsiolkovsky statue in Moscow.
Every extraterrestrial location can be logged only once. so, for example, the townhall of a certain town can not be used anymore if the entrance sign of that town has been used already. But several waymarks can be created for the same extraterrestrial location if there is more than match on Earth (like more than one Tziolkovsky statue in different places).
The name must represent a non-commercial entity, like a real or fictional person or a geographical name! so, please no Sirius-Radios, Mars-Chocolate-bars, Sun-Laundry-soap, Saturn-car dealerships, or Moon-pies.
The extraterrestrial location must be natural. No satellites, space probes, Mars rovers or UFOs please.
Some websites that might help you
The US Geological Service has a list of thousands of features throughout the solar system. so, if you know a statue of a famous person, chances are, that name is listed here.
The USGS list does not include comets. Most of those are named after their discoverer and Wikipedia has a comprehensive list.
If you want to get really detailed, check out the Lunar and Planetary Institute. It has maps of Mercury, Venus, Mars and the Moon as well as a detailed databases of Venus, Ganymede and Callisto.
Here is a map of the solar system with all registered locations:
