Detailed Description

Abstract base class for all celestial targets.

Target is the unified concept for anything in the sky that can be pointed at from an observer location. Concrete implementations cover:

• DirectionTarget — fixed spherical direction in any supported frame (ICRS, equatorial, ecliptic). Aliased as ICRSTarget, etc.
• StarTarget — adapter for Star catalog objects
• BodyTarget — solar-system bodies (Sun, Moon, planets)
• *(future)* SatelliteTarget — Earth-orbiting satellites (TLE/SGP4)

Every Target carries a human-readable name(). Use std::unique_ptr<Target> to hold heterogeneous collections.

Example

auto sun = std::make_unique<siderust::BodyTarget>(siderust::Body::Sun);
std::cout << sun->name() << "\n";           // "Sun"
qtty::Degree alt = sun->altitude_at(obs, now);
 
// Polymorphic usage
std::vector<std::unique_ptr<siderust::Target>> targets;
targets.push_back(std::move(sun));
targets.push_back(std::make_unique<siderust::StarTarget>(VEGA));
for (const auto& t : targets) {
    std::cout << t->name() << ": " << t->altitude_at(obs, now) << "\n";
}
