An Orbit Map of the Solar System
This week’s map shows the orbits of more than 18000 asteroids in the solar system. This includes everything we know of that’s over 10km in diameter - about 10000 asteroids - as well as 8000 randomized objects of unknown size. This map shows each asteroid at its exact position on New Years’ Eve 1999. All of the data for this map is shared by NASA and open to the public.

Really lovely stuff!

The ultimate off-site backup

So assuming the mission continues well, in 2014 the Rosetta Probe will land on Comet 67P/Churyumov-Gerasimenko, where it will measure the comet's molecular composition. Then it will remain at rest as the comet orbits the sun for hundreds of millions of years. So somewhere in the solar system, where it is safe but hard to reach, a backup sample of human languages is stored, in case we need one.

As jwz says: 'The Rosetta Disc is now safely installed on 67P/Churyumov-Gerasimenko.'

Sweden Solar System
the world's largest permanent scale model of the Solar System. The Sun is represented by the Ericsson Globe in Stockholm, the largest hemispherical building in the world. The inner planets can also be found in Stockholm but the outer planets are situated northward in other cities along the Baltic Sea. The system was started by Nils Brenning and Gösta Gahm and is on the scale of 1:20 million.
