Jump map from Travellermap.com

Yurat does not meet the criteria for any standard classification.

• This world is a "Twilight Zone World", a planet that is tidally-locked to its star. It has a hot side that permanently faces the star, a cold side that permanently faces away, and a narrow twilight zone in-between.
• It is an unclaimed Non-Aligned world located in the Sithula Subsector of Divide Sector.

System Data

Orsa-Yurat System

The primary is Orsa, an ordinary red main sequence star. It has a luminosity of 0.0268 Sols, a mass of 0.4258 Sols, and a diameter of 658,000 km. (I) Yurat orbits within the habitable zone and is designated the mainworld. (II) a trace atmosphere hospitable world, (III) an exotic atmosphere stormworld, (IV) an exotic atmosphere bigworld, and (V) a trace atmosphere iceworld form the outer system. Many of the worlds retain satellites.

Mainworld Data

(I) Yurat

(I) Yurat is designated the mainworld. It orbits Orsa at a mean distance of 0.17 AU (25.4 million km), within the habitable zone. It has an orbital period of 39 days 6 hours: it is tidally locked to Orsa. The axial tilt is 5 degrees. Yurat has a diameter of 4,250 km, a density of 3.84 g/cm³, and a surface gravity of 0.23 G. The world is geologically inert. Its atmosphere is rated as Very Thin, Tainted, with a mean surface pressure of 0.19 bar and a composition of 90% nitrogen (N₂), 8% abiotic oxygen (O₂), 1% carbon dioxide (CO₂), and 1% argon (Ar), water vapor (H₂O), neon (Ne) and other trace gases. The taint is caused by the low percentage of atmospheric oxygen and large amounts of airborne silicates and dust. Approximately 42% of the surface is covered in seas of liquid water: average tidal ranges exceed 0.3m. Mean surface temperature: 11°C. The atmosphere is sluggish and weak weather systems driven by the star and the seas drift across the globe. The climate is static.

Mainworld Geography and Topography

Total surface area: 57 million km², Land surface area: 33 million km², Water surface area: 24 million km².

• The oxygen in the atmosphere is abiotic in origin, produced by the photocatalytic reaction between the high levels of UV energy radiating from the star and titanium dioxide (TiO₂), which is found in surface minerals such as ilmenite.

Native Lifeforms

No world in the Yurat system is known to have native life.
