Planetensuche Astronomy Software
Planetensuche is a comprehensive, free desktop application designed for amateur astronomers, space enthusiasts, and researchers. It integrates vast astronomical databases with powerful visual exploration tools, interactive sky maps, and realistic orbital simulations.
Core Features & Modules
🪐 Exoplanet & Stellar Catalog Database
- Vast Catalogs: Embedded database with up-to-date exoplanet discoveries (NASA Exoplanet Archive, Gaia DR3, TESS TOI/CTOI, Kepler, SIMBAD).
- Broad Scope: Explore exoplanets, galaxies, dwarf planets, asteroids, and variable stars (AAVSO, VSX).
- Habitability Analysis: Calculate Earth Similarity Index (ESI) and filter by circumstellar habitable zones (Kopparapu 2013 models).
- Binary Star Matching: Cross-reference catalog data to identify binary and multiple stellar systems.
📊 Data Visualization & Analytics
- Over 70 Interactive Charts: Compare planetary masses, radii, orbital periods, discovery methods, and stellar spectral types (including HR Diagrams).
- Estimation Tools: Built-in calculators for estimating stellar radius and mass based on observational parameters.
- Lightcurve Import: Plot and analyze transit dips directly from TESS and Kepler photometry data.
🌌 Interactive Star Map & Simulations
- Dynamic Sky Map: Interactive celestial map highlighting constellations, deep-sky objects, and exoplanet host stars.
- Orbit Simulator: Observe exoplanets in realistic orbits around their host stars or build custom planetary configurations.
- Observing Planner: Tracks sunrise/sunset, moon phases, comets, and night sky quality (Bortle & SQM metrics).
🎓 Education & Extras
- Astronomy Quiz: Test your knowledge about space, distances, and planetary facts with a built-in educational quiz module.
- Formula Collection: A handy reference section for common astronomical formulas and physical calculations.
- History of Exoplanet Hunting: Detailed timelines and information regarding milestones in exoplanet research (View timeline →).
⚙️ Technical Architecture
- Offline First: Fully standalone execution at the telescope without requiring internet connectivity.
- Modern Java: Built with Java 21 (LTS) & JavaFX for responsive performance and fluid rendering.
- Cross-Platform: Runs smoothly across Windows, Linux, and macOS.
- Multilingual UI: Supports German, English, French, Spanish, and Italian.
