Orto IV is a gas giant planet. It orbits fourth around the primary sun of the Orto system in the Sluis sector. The planet's atmosphere is composed of mostly hydrogen and helium, the two most common elements in the universe, with some trace elements. There have been several surveyor probes sent to the planet to determine if there is a solid core underneath the gas; all ceased operations before they reached the center of the planet. This planet does possess an active magnetic field, which may play a role in the disappearance of the probes. Also, Orto IV does, from time to time, emit random bursts of electromagnetic radiation, usually in the form of x-rays. The planet's history is a cloudy one. There are no galactic records for the planet, and all of the scientific information comes from a single probe. There are plans for further exploration but are on hold now for economic reasons.
