Orbital character
A strongly elongated path around the Sun
Hale–Bopp follows a catalogued path with a 182.8 AU semi-major axis, eccentricity 0.995, and 89.4° inclination. The resulting two-body period estimate is 2,471.521 Earth years; the representation notes below state the source epoch and precision boundary used by Explore.
Catalogue context
Hale–Bopp among its nearest Helios peers
Hale–Bopp is linked with Halley, Encke, 67P/Churyumov–Gerasimenko, NEOWISE, Tempel 1 inside the Helios comet selection. The grouping keeps adjacent reading coherent; it does not imply that these bodies share the same composition, origin, or present physical state.
