A huge gas giant on the outskirts of the Manpha system, there is nothing terribly unique to Manpha IV. It is a fairly standard gas giant while its orbit lies very close to that of its sister planet, Manpha III. Due to this proximity, the two planets have been modifying each other's orbits and inching their way towards each other as the centuries pass. Scientists have calculated that within several millennia the two will collide, but at this stage, it is unknown if they will simply fragment, or if they will merge and create a second star and change the Manpha system into a binary star system.
