Astronomy AI tool for the Laravel AI SDK — moon phases, sunrise/sunset, planet positions, eclipses, night sky reports. Part of the OpenCompany AI tool ecosystem.
Give your AI agents the ability to perform real-time astronomical calculations. Built on astronomy-bundle-php (Jean Meeus' Astronomical Algorithms) and the AI Tool Core framework.
OpenCompany is an AI-powered workplace platform where teams deploy and coordinate multiple AI agents alongside human collaborators. It combines team messaging, document collaboration, task management, and intelligent automation in a single workspace — with built-in approval workflows and granular permission controls so organizations can adopt AI agents safely and transparently.
This celestial tool is one example of how AI agents can be extended with specialized capabilities beyond standard LLM knowledge — giving agents accurate, real-time astronomical data instead of relying on training data that may be outdated or imprecise.
OpenCompany is built with Laravel, Vue 3, and Inertia.js. Learn more at github.com/OpenCompanyApp.

useLaravel\Ai\Facades\Ai;
useOpenCompany\AiToolCelestial\Tools\QueryCelestial;
useOpenCompany\AiToolCelestial\CelestialService;
// Create the tool$tool = newQueryCelestial(

// Use with an AI agent$response = Ai::agent()
->tools([$tool])
->prompt('What phase is the moon in right now?');If you have ai-tool-core installed, the tool auto-registers with the ToolProviderRegistry:
useOpenCompany\AiToolCore\Support\ToolProviderRegistry;
$registry = app(ToolProviderRegistry::class);
$provider = $registry->get('celestial');
// Create tool with context$tool = $provider->createTool(
\OpenCompany\AiToolCelestial\Tools\QueryCelestial::class,
['timezone' => 'America/New_York']
);You can use CelestialService directly without the AI tool wrapper:
useOpenCompany\AiToolCelestial\CelestialService;
$service = app(CelestialService::class);
// Moon phaseecho$service->moonPhase(null, 'Europe/Amsterdam');
// Sunrise/sunset in Amsterdamecho$service->sunInfo('2025-06-21', 52.3676, 4.9041, 'Europe/Amsterdam');
// All planets visible from Berlinecho$service->planetPosition('all', null, 52.524, 13.411, 'Europe/Berlin');
// Night sky reportecho$service->nightSky(52.3676, 4.9041, 'Europe/Amsterdam');
// Solar eclipse checkecho$service->solarEclipse('2026-08-12', 40.7128, -74.0060);
