Sylva is a Terran Planet in Astroneer, with the moon Desolo orbiting it. It is the third planet, as well as the starting planet, with everything a player needs to begin their adventure. It has an average atmosphere and is overall very temperate and pleasant. Power generation on Sylva is balanced enough for the player to effectively use solar panels, wind turbines, or generators. The Medium Generator is not reliable early on due to Tungsten not being available on Sylva. However, working Medium Generators can sometimes be found on wrecks underground, allowing the player access before being able to obtain tungsten.

Physical characteristics[edit | edit source]

Sylva is the Astroneer analog of Earth, featuring several distinct biomes. Much of the planet's surface is covered by plains and forests, providing a natural habitat for a lush population of flora, giving the planet an overall green appearance. There are also rocky mountains with little vegetation. Long, deep ravines may also be found across the planet's surface, making travel in some areas dangerous.

Below the surface, an expansive cave system stretches to the outer core, with a large mantle-layer cavern filled with giant mushrooms.

Sylva has a transparent atmosphere with a slight blueish hue, thick white clouds form an intermittent layer above the ground.

Minerals

Abundant deposits of compound and resin are scattered around Sylva's surface. On the plains, occasional deposits of clay can be encountered, whereas some forests harbor ammonium. Graphite layers surround some of the ravines and in the mountains, malachite veins can be found.

In the lower layers of Sylva's crust and mantle, rich veins of quartz, laterite, sphalerite, and malachite offer sufficient resources to prepare for other adventures.

Flora[edit | edit source]

Sylva has a generous amount of flora available across the planet. The plains, hills, and forests give home to numerous plants, including trees, ferns, and grasses. As such, plenty of organic can be harvested.

Hazardous flora also can be found around Sylva. Bouncevine may be found on the mountain slopes, while Popcoral, Daggeroot and Hissbine are found underground, with Popcoral being more common.

AstroWiki Warning.svg Spoiler Warning: Information below contains information that may ruin your enjoyment of discovering the game's secrets for yourself. Proceed at your own risk.

Sylva has six Gateway Chambers, each requiring 5U/s of power for 30 seconds to be activated. At least one must be activated before the player can access the Gateway Engine in the core of the planet.

Once a Gateway Chamber has been activated, the Gateway Engine opens in the core. Placing a single Quartz in one of the slots reveals the Geometric Triptych. Placing the Geometric Triptych in the slot on the opposite side (above you) will activate the engine, revealing the Odd Stone and allowing teleportation to the core as well as revealing the inactive node for the Gateway Portal if it has not yet been discovered.

Trivia[edit | edit source]

  • Unlike Earth, Sylva does not seem to feature distinct climatic zones – apart from the difference between lush plains and forests and a less habitable mountainous climate. There are no polar ice shelves and neither are there deserts. Furthermore, the same plant species can be found throughout the planet.
  • On a related note, since there is no axial tilt relative to the ecliptic, Sylva will not experience any seasons.
  • Another key difference is the complete absence of water on Sylva (as in the game in general). Hydrogen can be obtained from the atmosphere and there are white clouds similar to Earth's, so there may be water vapor present. However, without actual groundwater, the forests on Sylva would quickly perish – unless they have adopted an efficient way to source water from the air.
  • Sylva's moon Desolo orbits Sylva extremly slowly, at least compared to the orbital periods of planets and Shuttles. On the other hand, Sylva's orbital period around the Sun is relatively short (even shorter than its rotational period). As a result, on Sylva, each day is about six times as long as a (solar) month.
  • Since Desolo's orbit is not inclined relative to the ecleptic, each new moon on Sylva is a solar eclipse, and each full moon a lunar eclipse. Furthermore, since all planets orbit in the same plane, are extremely large (compared to the Sun) and are pretty close to one another, the inner planets also eclipse the Sun fully when seen from Sylva.
