At Quaoar.
Measured
- Goes round once every
- 11.7 days
- Distance from Quaoar
- about 13,518 km (its orbit's average)
- Orbit
- backwards (retrograde), inclined 154°, eccentricity 0.253

How far, from the Earth
About 43.3 AU. To cross it:
- Light6 hours
- Voyager 1's speed12.2 years
- Driving at 100 km/h7,380 years
Voyager 1 at the speed it moved outward over the year to 2026-10-25 (JPL Horizons). Driving: nonstop, never refuelling.
Facts
- Its size is not well measured.
- The orbit here is JPL Horizons', fitted to few observations. A 2025 study puts its period at about 12.4 days, nearly circular (arXiv 2510.12495).
