Comet
1P/Halley
The comet that proved comets return — met in flight by ESA’s Giotto in March 1986; next at perihelion in 2061.
- Mean distance
- 17.83 au
- Orbital period
- 75.32 y
- Diameter
- 11 km
Values: JPL small-body database (1P/Halley) · ESA Giotto mission pages — not network-verified in this run.
Listed without a figure position: JPL small-body orbital elements were not importable in this environment, and no position is invented.
Recorded encounters
- 1986 GiottoGiotto passes through the coma of 1P/Halley
An encounter sequence is the order the records give, not a flight path. Atlas holds no trajectory for these missions and draws none.

Schematic view: distances are log-compressed (to true scale Neptune sits 30× Earth’s distance) and discs are ranked by size, not to scale. Positions computed from JPL mean orbital elements for today — an orientation good to a few degrees, not an ephemeris.
