I have a question concerning AstronomicalData
. If I want the declination of the moon for a given date, I use:
AstronomicalData["Moon", {"Declination", DateObject[{1985, 11, 4}]}]
(* Quantity[27.0, "AngularDegrees"] *)
so this works very well.
When I try to obtain the longitude of the ascending node for a given date:
AstronomicalData["Moon", {"AscendingNodeLongitude", DateObject[{1985, 11, 4}]}]
Mathematica tells me that {"AscendingNodeLongitude", {1985, 11, 4, 0, 0, 0.}} is not a known property
, but it is listed in the list of properties.
Can someone tell me what I do wrong here ? How can I get the longitude of the ascending node for a given date?
AstronomicalData
has been superseded byPlanetData
,StarData
, etc. After some digging, I found that the following syntax works for some properties:Entity["PlanetaryMoon", "Moon"][Dated["AngularDiameterFromEarth", Yesterday]]
, IN particular, it works for properties that change in time, but it returns an unclear error for immutable properties (like e.g. the name of the satellite). $\endgroup$
