## Parameters
Provide `days` or `lunarDistances`.
- `days` — Optional. From now through this many days, 1 to 365. Default 60.
- `lunarDistances` — Optional. Only approaches within this many Moon distances, 0.1 to 100. Default 10.
- `limit` — Optional. Rows to return, from 1 to 20. Default 10.
## Examples
- `GET https://api.duaer.com/v1/data/close-approaches?days=60&lunarDistances=10` — flybys within ten lunar distances in 60 days.
- `GET https://api.duaer.com/v1/data/close-approaches?days=365&lunarDistances=1` — objects passing closer than the Moon this year.

The response is `{ "items": [...] }`. Each item has `source`, `title`, `url`, and `summary`, plus:
- `designation`, `fullName` — object.
- `closeApproachUtc` — time of closest approach.
- `distanceAu`, `distanceKm`, `distanceLunar` — nominal distance.
- `relativeSpeedKms`, `absoluteMagnitude`, `diameterKm` — speed, brightness, and size when known.
Fields without a value are left out.
