New page

== Asterra Star System ==

**Primary Star:** Asterra
**Stellar Type:** G-type main sequence (cool yellow)
**Mass:** 0.93 Sol
**Luminosity:** 0.78 Sol
**Radius:** 0.95 Sol
**Estimated Age:** ~7.1 billion years
**Stellar Activity:** Low flare rate
**Habitable Zone:** 0.62–0.74 AU

The Asterra star system is dynamically stable and long-settled.
Most permanent infrastructure predates the loss of Ytharia and was designed for extended autonomous operation.

== System Scale ==

* Inner system boundary: ~0.1 AU
* Primary asteroid belts: 2.4 AU and 6.8 AU
* Outer planetary boundary (Helior): ~38 AU
* Effective heliopause influence: ~95 AU

Traffic followed fixed corridors enforced by orbital control infrastructure.

---

== Planetary Order ==

=== 1. Keth ===

**Type:** Rocky (terrestrial)
**Orbital Radius:** 0.21 AU
**Orbital Period:** 41 standard days
**Rotation:** Tidally locked
**Mass:** 0.62 Earth
**Surface Gravity:** 0.78 g
**Atmosphere:** ~0.2 bar, volatile-poor
**Mean Dayside Temperature:** ~620 K
**Mean Nightside Temperature:** ~190 K
**Moons:** None

Keth exhibits permanent hemispheric contrast.
The dayside is exposed to continuous stellar radiation.
The nightside remains cold and shielded.

==== Keth Mining Operations ====

Mining activity was restricted to the nightside.

* Operational depth: 300–1200 m
* Facilities: Subsurface, hardened
* Automation level: High
* Permanent staffing (peak): <400 system-wide
* Power: Orbital solar collectors and compact reactors

Keth was never intended for habitation and functioned solely as an inner-system industrial node.

=== 2. Ytharia ===

**Type:** Rocky (ocean-dominated terrestrial)
**Orbital Radius:** 0.68 AU
**Orbital Period:** 286 standard days
**Axial Tilt:** 18.4°
**Mass:** 1.08 Earth
**Surface Gravity:** 1.02 g
**Surface Water Coverage:** ~82%
**Mean Surface Temperature:** ~284 K
**Atmosphere:** ~1.4 bar, moisture-rich
**Moons:** Two

Ytharia was the only planet in the Asterra system known to support complex native life.

==== Ytharia Orbital Station ====

A major orbital station operated in high orbit.

* Orbital altitude: ~42,000 km
* Primary ring diameter: ~11 km
* Permanent population (pre-loss): ~180,000
* Berths: ~60 capital-class vessels

The station functioned as the primary spaceport, customs hub, manufacturing center, and traffic control node for the system.

---

=== Moons of Ytharia ===

==== Elaris ====

**Classification:** Major moon
**Radius:** ~1,720 km
**Mass:** 0.94 Luna
**Orbital Distance:** ~410,000 km
**Orbital Period:** 34.6 days

Elaris governed Ytharia’s primary tidal cycles and stabilized axial tilt.

===== Elaris Lunar Base =====

* Population capacity: ~25,000
* Launch mass throughput: ~4.2 million tons per year
* Primary functions:

* Deep-space observation
* Orbital traffic support
* System monitoring

Low seismic activity enabled long-duration operations and sensitive instrumentation.

---

==== Tirien ====

**Classification:** Minor moon
**Radius:** ~420 km
**Orbital Distance:** ~610,000 km
**Orbital Period:** 69.2 days
**Orbital Resonance:** 2:1 with Elaris
**Inclination:** 3.1°

From Ytharia’s surface, Tirien was frequently occluded by Elaris and visible only during specific alignments.

---

=== 3. Vael ===

**Type:** Gas giant
**Orbital Radius:** 3.1 AU
**Orbital Period:** 5.4 years
**Mass:** 1.9 Jupiter
**Magnetosphere Radius:** ~9 million km
**Moons:** 40+ confirmed

Vael’s magnetosphere deflected a significant fraction of cometary and interstellar debris, contributing to inner-system stability.

---

=== 4. Orthis ===

**Type:** Gas giant
**Orbital Radius:** 7.6 AU
**Orbital Period:** 20.9 years
**Mass:** 1.2 Jupiter
**Ring Radius:** ~140,000 km
**Moons:** 30+

Several moons show evidence of subsurface oceans or cryovolcanic activity.

==== Orthis Orbital Station ====

* Orbital altitude: ~1.8 million km
* Population (peak): ~95,000
* Annual material throughput: ~120 million tons

The station served as the primary logistical hub for asteroid and moon mining operations in the middle system.

---

=== 5. Ceryn ===

**Type:** Gas giant
**Orbital Radius:** 14.2 AU
**Orbital Period:** 53.6 years
**Mass:** 0.7 Jupiter
**Moons:** Irregular and partially captured

Orbital characteristics indicate major disruption approximately 1.3 billion years ago.

---

=== 6. Helior ===

**Type:** Gas giant
**Orbital Radius:** 38 AU
**Orbital Period:** ~235 years
**Mass:** 0.4 Jupiter
**Moons:** Sparse, frozen satellites

Helior marks the outer boundary of significant planetary mass in the system.

---

=== 7. Nysa ===

**Type:** Rocky (cold terrestrial)
**Orbital Radius:** 62 AU
**Orbital Period:** ~490 years
**Mass:** 0.31 Earth
**Surface Gravity:** 0.55 g
**Atmosphere:** <0.1 bar, frozen trace gases
**Mean Surface Temperature:** ~95 K
**Moons:** None

The lack of satellites is attributed to early orbital instability and gravitational interference from outer gas giants.

---

== Infrastructure Summary ==

* Fixed installations designed for 200–400 year service lifespans
* Automation rates exceeded 80% beyond 3 AU
* Traffic density decreased sharply past Orthis

---

== Canon Status ==

The Asterra system is no longer governed as a unified political entity.
Persistent infrastructure remains active where power, supply, and personnel allow.
Ytharia remains the system’s historical and cultural origin point.

If you want, next we can:

* Lock **population numbers**
* Define **military assets by orbit**
* Write **The Loss of Ytharia** with dates and hard consequences
* Create **internal wiki templates** so future pages stay consistent

Just say the word.
