I have been watching this "object" for 6+ years now. It has grown dramatically in size and brightness, especially now. It was stated in National Geographic that it was closest to Earth in Sept 2010 and would not be that close again until 2022. If that is the case, then why has it grown larger and brighter recently. Does larger and brighter not mean closer? Perhaps it has something to do with the plutonium that was sent there.
