# ST_Distance

Returns the minimum geodesic distance between two geography objects in meters. Uses S2 geometry-to-geometry distance (`S2ClosestEdgeQuery`), which computes the true minimum distance between any two points on the geometries — not centroid-to-centroid.

## Signatures

```sql theme={"system"}
ST_Distance (A: Geography, B: Geography)
```

## Parameters

<ParamField body="A" type="Geography" required>
  The first geography.
</ParamField>

<ParamField body="B" type="Geography" required>
  The second geography.
</ParamField>

## Return type

<ResponseField type="Double">
  The minimum geodesic distance between A and B, in meters.
</ResponseField>

## Example

```sql theme={"system"}
SELECT ST_Distance(
  ST_GeogFromWKT('POINT (0 0)'),
  ST_GeogFromWKT('POINT (1 1)')
);
```

```
157249.59847404022
```

The result is approximately 157 km, the great-circle distance between (0,0) and (1,1) on the WGS84 sphere.
