Kerbal Star Systems Wiki

Naal is the 8th planet to be discovered, and the first planet to be discovered before it was sighted. It is an ice giant, like Oran and Hypat, and a member of the outer planets.

In-game Description

"Naal is the second last giant planet in the Kerbol system, and is an ice giant like Oran. Naal’s discoverer, Nelly Kerman, was attempting to win a bet to find a giant marshmallow in space with his friend during the time of discovery. He was disappointed that he lost the bet, but at least he managed to find a new planet, right? Naal has one of the most turbulent atmospheres in the entire Kerbol System, with wind speeds in excess of the speed of sound, so don’t plan on entering the atmosphere anytime soon! Even if the sight of Naal isn’t enough of a reason for you to plan a mission there, the system of moons is more than worth a visit."

Physical Characteristics

Naal is an ice giant bordering the outer planets from the debris outside its orbit. It gets its blue tint from large quantities of methane and ammonia inside its atmosphere. The planet experiences significant internal heating inside its liquid methane-ammonia "mantle", and like other ice giants, this temperature difference drives high speed winds across the surface that can exceed the speed of sound.


Naal's atmosphere, like most ice giants, is composed of hydrogen, helium, and methane. The concentrations of methane in Naal's atmosphere is what gives it its distinct dark blue color.

One of Naal's characteristic features is that winds on the surface, caused by movements in the mantle, are extremely high, and can even exceed the speed of sound. As a result, crafts would have to be resilient to wind to be able to descend into the depths of Naal.


Naal has faint, dark rings made of fine dust. These may have been remnants from Naal's formation, or simply dust left off by nearby moons. They are mostly shepherded by Thes.

History and Observation

Naal was discovered by Nelly Kerman in the year 3692. A few decades before that, it was mathematically predicted by a group of astronomers nearby using perturbations in Oran's orbit. That makes Naal the first planet to be discovered using the power of Math.

Naal was almost discovered accidentally by Galileo Kerman, who was observing Jool at the time and Naal just happened to be in view nearby. He mistook it for a blue star, however, and it wasn't until years later that Naal was found to be an actual planet.


Naal currently has 3 moons:
