SyntaxThe SolarSystemBody type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | SolarSystemBody | Creates a SolarSystem object to which a pre-configured Ephemeris object can be added |
| SolarSystemBody(Body) | Create a SolarSystem object for a specified target body |
| SolarSystemBody(SolarSystemBodyOrbitDataSource, String) | Initializes a new instance of the SolarSystemBody class |
Properties| Name | Description | |
|---|---|---|
 | Ephemeris | Ephemeris object used by comet and asteroid calculations. |
| Name | Name of the body |
| Refraction | True to create coordinates corrected for refraction. (Only used by AltAzCoordinates(DateTime).) |
| SiteHeight | Site height (metres) |
| SiteLatitude | Site latitude (North positive) |
| SiteLongitude | Site longitude (East positive) |
| SitePressure | Site pressure (Hectopascal or millibar) |
| SiteTemperature | Site temperature (Celsius) |
Methods| Name | Description | |
|---|---|---|
| AltAzCoordinates | Return the body's topocentric coordinates at a given time |
| AstrometricCoordinates | Return the body's astrometric coordinates at a given time |
| GeoCentricPosition | Returns the body's geocentric position and velocity vectors |
| HelioCentricPosition | Returns the body's heliocentric position and velocity vectors |
| TopocentricCoordinates | Return the body's topocentric coordinates at a given time |
Remarks
This is an easy to use tool that provides coordinates for major solar system bodies. Internally it uses the JPL DE421 ephemeris data contained within the NOVAS component.
Pluto is included for convenience even though it is no longer recognised as a major planet by the IAU.
