## Summary
Iridium 47 is an artificial satellite catalogued under international designation 25106. It belongs to the Iridium constellation of communication spacecraft.

## Key Facts
- International designator: 25106
- Instance of: artificial satellite
- Member of: Iridium satellite constellation
- Wolfram Language entity: Entity["Satellite", "25106"]

## FAQs
### Q: What is Iridium 47?
A: Iridium 47 is one of the roughly 66 operational satellites that form the Iridium low-Earth-orbit voice and data relay network.

### Q: How is Iridium 47 identified in technical databases?
A: The satellite is tracked by the international catalogue number 25106 and can be referenced in Wolfram Language as Entity["Satellite", "25106"].

### Q: Is Iridium 47 still part of the active constellation?
A: Source material does not specify current operational status; only the catalogue number 25106 and its classification as an artificial satellite are confirmed.

## Why It Matters
Because the Iridium system provides pole-to-pole voice and data links for maritime, aviation, defense, and emergency services, every satellite—including Iridium 47—contributes to global coverage. Losing track of even one member would create gaps in the 66-satellite Walker constellation geometry, so the unique catalogue number 25106 is a key identifier for space situational-awareness teams, network operators, and researchers modelling orbital debris risk. For historians, the numeric sequence also helps date the launch epoch within the overall 1997-2002 Iridium deployment campaign.

## Notable For
- Carries the catalogue identifier 25106, making it easy to cross-reference in public satellite databases
- Part of the original 66-satellite Iridium architecture that pioneered commercial handheld satellite phones
- Serves as a representative example when teaching orbital mechanics of LEO communication constellations
