The MRC Gravitational System Solver

Analyze one body, build a multi-body system, create custom body specifications, search astronomical catalogs, and run MRC candidate-membership research. External services supply raw identity, mass, radius, position, epoch, and provenance only. MRC produces all derived results.

Single-Body MRC Analysis

The original frozen MRC Core remains available for one-body boundary analysis.

Multi-Body MRC Analysis

Add two or more installed Solar System bodies or temporary custom bodies.

Solar System positions and raw velocities come from synchronized NASA/JPL Horizons state vectors at the selected epoch. Position drives the static MRC calculation. Raw velocity is used only in the separate observed trajectory analysis and does not replace any MRC-derived result.

Custom Bodies

Create and save reusable bodies for Multi-Body analysis. A Custom Body can represent a real Solar System object, spacecraft, hypothetical object, fictional body, or any manually defined object. Saving a Custom Body never changes the permanent Solar System catalog.

Saved Custom Bodies remain separate from the installed Solar System catalog. Solar System candidates borrow from the unresolved distributed-mass remainder only during the active calculation. External or flyby bodies leave the Solar System remainder untouched and expand only the custom-body runtime boundary. Select NASA/JPL Horizons to retrieve fresh synchronized Cartesian position and raw velocity data at the simulation epoch.

Search Astronomical Catalogs

Search by object name. The engine resolves identity and available scientific data, then lets you transfer the result into Custom Bodies so you can review it, complete any missing fields, and save it for Multi-Body analysis.

Internal MRC logic remains on the Mercy Systems server and is not delivered to the browser.
