Estra (Celestial Classification HH-001P3) is a Gaian terrestrial planet and the third planet in the Sol star system, located centrally within the Human astral territory. As the home planet of the Humans, Estra is a major intergalactic hub for politics, trade, transport and social gathering. One moon named Nulla orbits the planet, reflecting starlight from Sol onto its surface even at night.
The planet's unique conditions mean it features a diverse range of climates, making it a naturally comfortable environment for all races and wildlife alike. Although some aspects of the climate conditions have changed and worsened as a result of rapid industrialisation and increased levels of greenhouse gases within the atmosphere, immense efforts to overturn these changes have largely succeeded.
Two organisations of note with their main headquarters based on Estra are The Journalists and Wilde Manufacturing Co., both of which have primarily Human-based backgrounds. Free trade laws within the Sol star system also mean that based on the planet are a wide variety of smaller businesses as well.
