The construction of artificial planets as a possible method of obtaining habitable locations for the long term development of human society would be a logical progression from either terraformed planets or large colonies of the O'Neill type. While clearly any discussion of such systems would be speculative, it is possible to consider some key high level trade offs for artificial planets. It is concluded that an object with a large platinum, iridium, and osmium core, which is about the size of the Moon but with a mass close to that of the planet Mars would be the optimum design. From this an outline of the main characteristics of such a planet is presented, together with some thoughts about its construction, development and viability. It is concluded that if artificial planets were ever to be produce they would need to be constructed by processes very different from those found in nature.
