The Lestra Star System is a captivating celestial ensemble, centered around a DC3 White Dwarf star. The system is home to five unique planets, each with its own distinct characteristics and phenomena. The first planet, Lestra 1, is a P4 class planet with a high gravity and a surface composed of a mix of Silicon, Iron, Magnesium, and Ice. The second planet is primarily composed of Lead and Uranium, with a high surface radiation level. The third planet is known for its atmospheric crystal networks and extreme surface conditions. The fourth planet, Lestra 4, is a class I planet with a large size and a unique landscape that is constantly changing due to its active crust. The fifth planet, Lestra 5, is a gas giant known for its diamond rain and superfast winds. Each planet in the Lestra Star System presents unique opportunities for scientific exploration and discovery, making it a fascinating system in the vast expanse of the universe.
Lestra 1
| Class: | P4 |
| Distance: | 1.33 AU |
| Period: | 1.32 Earth Years |
| Radius: | 8480.65 km |
| Gravity: | 2.6 G |
Lestra 1 is a P4 class planet situated 1.33 AU away from its star. It completes an orbit around its star in approximately 1.32 Earth years. The planet boasts a radius of 8480.65 km and a gravity of 2.6 G, significantly higher than that of Earth. The atmospheric pressure on Lestra 1 is immense, averaging at 50.66 MPa (megapascals), which is 500 times the sea-level atmospheric pressure on Earth. Despite the largely cold atmosphere, the surface temperature reaches a scorching 3000 degrees Celsius, rendering the planet inhospitable for most known forms of life. Lestra 1's composition is unique, consisting of a blend of Silicon, Iron, Magnesium, and Ice. This combination, along with the planet's extreme internal pressure and temperature, categorizes Lestra 1 as an exotic class P world. Although planets of this class are typically frozen, Lestra 1's unusually thick atmosphere and elevated internal conditions set it apart, making it a fascinating subject for astronomical and planetary studies.
Lestra 2
| Class: | P4 |
| Distance: | 2.12 AU |
| Period: | 2.67 Earth Years |
| Radius: | 10196.57 km |
| Gravity: | 0.9 G |
The second planet in the system is primarily composed of Lead and Uranium, with traces of Silicon. This unique composition gives the planet its distinct characteristics and makes it a subject of interest for scientists. The atmospheric pressure on the surface of this planet is 619,092 Pa, which is approximately 6.11 times the average atmospheric pressure at sea level on Earth. This high pressure, combined with the planet's chilling surface temperature of -174.8 degrees Celsius, creates a harsh and inhospitable environment. However, what truly sets this planet apart is its surface radiation level. At around 100 millisieverts per year, the radiation on this planet is a staggering six orders of magnitude higher than that on Earth's surface. This extreme radiation level, likely due to the planet's high Uranium content, poses significant challenges for exploration and potential colonization, but also offers unique opportunities for studying radiation-resistant life forms and the effects of radiation on planetary environments.
Orbiting this planet is the Solas Tempus Space Dock Class Station Hornet's Nest operated by the STMC.
Lestra 3
| Class: | E4 |
| Distance: | 3.43 AU |
| Period: | 5.49 Earth Years |
| Radius: | 13348.48 km |
| Gravity: | 2.2 G |
The third planet in the system is primarily composed of Osmium, Lead, Uranium, and Plutonium. This unique composition of heavy metals contributes to the planet's extreme conditions. The surface temperature reaches a staggering 41,640.21 degrees Celsius, which is several thousand times hotter than Earth's average temperature. This intense heat keeps much of the planet's surface in a molten state, with rivers of metallic plasma coursing across its landscape. The planet's atmospheric pressure is equally extreme, measuring at 6.9 YPa (yottapascals), a value that is several thousand times greater than Earth's atmospheric pressure. This high pressure and temperature result in heavy volcanic activity, further contributing to the planet's molten state. Despite these harsh conditions, the planet's surface radiation level is around 100 millisieverts per year, which is significantly higher than Earth's but comparable to the second planet in the system. This extreme environment, while inhospitable to known life forms, provides a unique opportunity for studying the effects of high pressure, high temperature, and high radiation on planetary geology and potential extremophile life forms.
Lestra 4
| Class: | I |
| Distance: | 7.07 AU |
| Period: | 16.22 Earth Years |
| Radius: | 17260.41 km |
| Gravity: | 2.57 G |
Lestra 4, a class I planet, orbits its star at a distance of 7.07 AU and completes an orbit every 16.22 Earth years. The planet's large size, with a radius of 17260.41 km, and a gravity of 2.57 G, sets it apart from many other known planets. However, what truly makes Lestra 4 unique is its atmospheric crystal networks. These vast networks of naturally occurring crystals float in the planet's atmosphere, constantly breaking and recombining along the atmospheric currents. As they catch and refract the light from the system's star, they create a dazzling array of colors across the sky, making Lestra 4 a visually stunning, yet inhospitable world.
Unique Features
- Magnetic Anomalies
- The planet's core is composed of a unique blend of metals that create intense magnetic fields. These fields result in spectacular magnetic anomalies, causing dramatic auroras that are visible even during the day and affecting the operation of electronic equipment. These anomalies make Lestra 4 a challenging environment for exploration but also a fascinating subject for scientists studying magnetism and its effects on planetary environments.
- Atmospheric Crystal Networks
- The planet has vast networks of naturally occurring crystals that float in the planet's atmosphere. These crystal formations, carried by atmospheric currents, constantly break and recombine, creating an ever-changing spectacle. The crystals catch and refract the light from the system's star, creating a dazzling array of colors across the sky. This unique phenomenon, a result of the planet's unique atmospheric and mineral conditions, makes Lestra 4 a visually stunning world, despite its inhospitable conditions.
Lestra 5
| Class: | I |
| Distance: | 12.75 AU |
| Period: | 39.31 Earth Years |
| Radius: | 17964.91 km |
| Gravity: | 2.5 G |
Lestra 5, a class I planet, is a gas giant that orbits its star at a distance of 12.75 AU, taking 39.31 Earth years to complete one orbit. With a radius of 17964.91 km and a gravity of 2.5 G, it is a large and massive planet, reminiscent of gas giants like Uranus or Neptune in our own solar system. The planet is known for its extreme atmospheric phenomena, including diamond rain caused by the high pressure and temperature conditions, and superfast winds that create long-lasting storms. These unique characteristics make Lestra 5 a fascinating subject of study, offering insights into the diverse range of conditions that can exist on planets in the universe.
Unique Features
- Diamond Rain
- Similar to what scientists believe occurs on Neptune and Uranus, Lestra 5 experiences "diamond rain" within its atmosphere. This is a result of the extreme pressure and temperature conditions within the planet's atmosphere, which cause methane to decompose and reassemble into pure carbon, which then crystallizes into diamonds. These diamonds then fall through the atmosphere like rain, eventually settling into the planet's core.
- Superfast Winds
- Lestra 5 has incredibly fast winds that reach speeds several times faster than the strongest hurricanes on Earth. These winds whip around the planet, creating massive storms that can last for years or even decades. The high wind speeds are a result of the planet's rapid rotation and the intense heat from its core, which creates strong convection currents in the atmosphere.
