# Gaspra

*In the Solar System*

A small stony asteroid in the inner belt, here because it was the first asteroid anybody ever photographed from close up: Galileo passed it in October 1991 and turned a point of light into a cratered, irregular object 18 km long. Every picture on this map of a rock that is not a smooth ball descends from that one.

| Radius | 6 km |
| Around the equator | 38 km |
| From the Sun | 377,825,355 km (+149,291 km/d) |
| From the Earth | 526,521,833 km (+363,065 km/d) |
| A signal takes | 29 min |

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.
