This illustration shows that the TW Hydrae protoplanetary disk is much wider than the size of our solar system. In fact, the gap in the TW Hydrae disk produced by a suspected planet resides 7.5 billion miles from the star. At this distance, the putative planet would orbit far beyond our Kuiper Belt, a reservoir of icy, leftover material from the formation of our solar system.
