The record

Product: SpaceEngine is a science-based, 1:1 scale Universe simulator and interactive 3D planetarium.
Universe exploration: It lets users travel seamlessly between celestial objects, from planetary surfaces to interstellar and intergalactic space, and change the flow of time.
Catalogs and generation: It represents known celestial objects using astronomical catalogs and procedurally generates objects in uncataloged regions.
Navigation and learning: The software includes object search, universe and planetary system maps, tutorials, and a built-in Wiki information system.
Graphics: Features include volumetric galaxy and nebula models, procedural planetary terrain, atmospheric scattering, eclipse shadows, auroras, and black-hole light warping.
Flight simulator: Its Flight Simulator mode supports spacecraft with Newtonian physics and pilot-assist autopilot, and is described as being in early development but usable.
VR: SpaceEngine supports Oculus and SteamVR headsets, while VR support is still a work in progress and controller support is partial.
Add-ons: Users can create and import add-ons such as catalogs, models, textures, and spacecraft, and share them through Steam Workshop.
Language support: The Steam page lists 18 supported interface languages and says additional localizations can be enabled in-game.
Commercial use: Commercial use requires purchasing the SpaceEngine PRO DLC in addition to the regular SpaceEngine copy; the soundtrack cannot be used commercially without permission from its copyright holders.
Software status: SpaceEngine is proprietary closed-source software, and the FAQ says there are no current plans to release its source code.
Support: The maker provides a support and general questions contact form, links to its manual, and invites users to join its Discord server.
Platform limits: The FAQ says console, Android, and iOS versions are not currently planned.
Company: The site identifies Cosmographic Software LLC as the maker; its pages opened for this research do not state a headquarters or founding year.
