Orbital Elements

Search for a target in the Viewer tab to populate this panel. Orbital elements pulled live from JPL Small-Body Database .

Quick Start

1Type a designation in the Target Lookup field above the tabs. Names, numbers, and provisional designations all work.

2Tap Search (or press Enter). The viewer queries JPL SBDB via a fallback proxy chain and renders the orbit in the Viewer tab.

3Drag the canvas to rotate the view. Scroll or pinch to zoom. The Data tab populates with the full orbital element set.

What You Can Search

Asteroid names :: Apophis, Bennu, Ceres, Vesta, Eros, Ryugu, Itokawa, Pallas

Asteroid numbers :: 99942, 101955, 1, 433, 134340

Provisional designations :: 2024 YR4, 2004 MN4, 2025 FA22

Comets :: 1P/Halley, 2P/Encke, 67P/Churyumov-Gerasimenko, C/2014 UN271

Interstellar objects :: 1I/Oumuamua, 2I/Borisov, 3I/ATLAS

Dwarf planets and centaurs :: Pluto, Eris, Sedna, Chariklo

Interaction Reference

Drag on the canvas (mouse or single-finger touch) :: rotate the 3D view. Horizontal drag spins around the ecliptic pole. Vertical drag tilts.

Scroll wheel or pinch two fingers :: zoom in and out. Range is roughly 20x in and 20x out.

PAUSE / PLAY :: freeze or resume time-evolution. Frozen view still rotates and zooms.

RESET :: snap back to the auto-fit zoom and default tilt for the loaded object.

ZOOM +/- :: discrete zoom steps for finger-friendly mobile use.

TOP :: snap to plan view (looking straight down on the ecliptic plane).

TILT :: snap to a 3D oblique view that exposes orbital inclination.

REFINE :: run N-body precision integration in a background worker. Replaces the Keplerian ellipse with the integrated trajectory (Sun + 8 planets + 1PN GR + Sun J2). Result is cached in IndexedDB; subsequent loads of the same object are instant. See the Data tab for the force budget and provenance manifest.

Speed selector :: time acceleration. 1x is real time (slow). 100x is roughly 100 simulation seconds per real second; useful for watching short-period orbits play out.

Orbital Elements Glossary

aSemi-major axis :: half the long axis of the ellipse. Sets orbit size and period (T = a^1.5 yr for heliocentric orbits in AU).

eEccentricity :: orbit shape. 0 = circle, 1 = hyperbolic (unbound, e.g. interstellar objects).

iInclination :: tilt of the orbit plane relative to the ecliptic, in degrees.

OmLongitude of ascending node :: where the orbit crosses the ecliptic going upward.

wArgument of perihelion :: orientation of the orbit in its own plane (from node to perihelion).

qPerihelion distance :: closest approach to the Sun. q = a(1 - e).

QAphelion distance :: farthest from the Sun. Q = a(1 + e).

MMean anomaly :: fictitious uniform angle parametrising time since perihelion.

MOIDMinimum Orbit Intersection Distance :: closest possible passage of the orbit to Earth's orbit (not the body itself). Key planetary-defence metric.

condCondition code :: JPL uncertainty grade. 0 is best (well-determined). 9 is worst (poorly constrained).

Troubleshooting

"Multiple matches" :: the JPL API returned several candidates. The status line lists up to four matching designations; try one of them exactly.

"Could not reach JPL API" :: all three CORS proxies failed. Usually a transient connection issue. Wait a minute and retry.

"Incomplete orbital elements" :: the object exists but lacks a fitted orbit (rare; usually very new discoveries). Try a different designation.

Orbit looks like a thin line :: high inclination viewed edge-on. Drag the canvas vertically to tilt and reveal the orbit shape.

Orbit doesn't fit on screen :: long-period comets or TNOs can have orbits up to 100+ AU. Use ZOOM- or...
