# Salacia

*In the Solar System*

A large Kuiper belt object with a moon called Actaea, here for its size and for almost nothing else: it has never been resolved into more than a point, its diameter comes from how much heat it radiates, and the mass comes from the moon's orbit. Between them they say it is dark and dense enough to be mostly rock. Whether it counts as a dwarf planet is unsettled, which is the usual state of affairs at this distance.

| Around the equator | 2,658 km |
| From the Sun | 6,787,567,644 km (+25,311 km/d) |
| From the Earth | 6,667,782,848 km (-1,081,785 km/d) |

Distances and speed are computed from JPL Horizons trajectories and are true of 2026-09-05, changing at the rate given beside each. The interpolation itself is good to a few kilometres; what ages these figures is the date, not the arithmetic.
