AU scale
Solar System planets fit inside tens of AU; nearby stars begin hundreds of thousands of AU away.
Nearby solar systems
Our Solar System inside the local stellar neighborhood.
A chart of nearby stars and planetary-system candidates around the Sun. Distances are shown in light-years, astronomical units, and kilometers so the scale is explicit.

Distance scale from the Sun
The chart keeps nearby stellar systems separate from Solar System planets and spacecraft.

Scale Notes
Why this chart is separate from the Solar System map
Light-year scale
At this scale the Solar System is a tiny origin marker, not a visible planetary layout.
Simulator link
Use the 3D space simulator for planetary and spacecraft scales, then this page for stellar-neighborhood scale.
Mathematical model
Astronomical scale-map model
Galaxy, void, and universe-scale charts use explicit distance conversions and scale mappings. They are schematic maps whose coordinates come from light-year, parsec, AU, or kilometer values.
Unit conversion
\[1\,\mathrm{ly}=63{,}241.077\,\mathrm{AU}=9.4607\times 10^{12}\,\mathrm{km}\]
Distances shown in multiple units are converted from fixed constants, so scale labels are mathematically traceable.
Display scale
\[x_{\mathrm{display}}=s\log\!\left(1+\frac{d}{d_0}\right)\]
Very large ranges may use a logarithmic or compressed map so nearby and distant objects can coexist. The compression is stated rather than hidden.
Volume approximation
\[V=\frac{4\pi R^3}{3}\]
Void and shell comparisons use spherical approximations where appropriate. The page labels this as an approximation, not an observed boundary mesh.
Verification standard: the rendered object must be reproducible from stated equations, catalog parameters, or explicit geometric transforms. Visual reference images may inform presentation only; they are not the source of orbital positions, field vectors, accretion-disk gradients, timing, or engineering layout.
Limitations: browser scenes may use bounded scale, compressed distances, simplified two-body dynamics, schematic transfer curves, or educational approximations where full numerical ephemerides, CFD, finite-element models, or general-relativistic ray tracing are outside the page scope. Those simplifications are part of the model contract, not hidden image-based construction.
