A possible consolation for those of us who would love to travel in Space but never shall is that even the Moon and Mars can come to us, at a price. Mars is close to the the Asteroid Belt so it is more likely than most planets to get hammered by collisions so violent that they propel lumps of the planet all the way to Earth. There may be lumps of other planets waiting to be identified in Earth's deserts but space probes have discovered less about what their chemical composition would be.
If you do obtain Lunar or Martian meteorite segments, think about how important you must be, in that lumps of other planets swirled about the Solar System for tens of thousands of years just so that they could come to your home. You can be Ming the Mercilless lording over your miniature space empire. Plebeian astronauts like Flash Gordon have to work so much harder.
There are fakes out there, though, so unless you are a geologist specialising in meteorites, it would be wise to buy from a dealer with a good reputation.
