# Dinkinesh

*In the Solar System*

A small main-belt asteroid, here because Lucy passed it in November 2023 as an engineering test and found a moon nobody had suspected - and the moon turned out to be two touching lobes, the first contact binary ever seen orbiting another asteroid. It is a reminder of how little a point of light gives away: everything interesting about this one was discovered in the four minutes it took to fly past.

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.
