angular_radius#
- sunpy.coordinates.sun.angular_radius(t='now')[source]#
Return the angular radius of the Sun as viewed from Earth.
The tangent vector from the Earth to the edge of the Sun forms a right-angle triangle with the radius of the Sun as the far side and the Sun-Earth distance as the hypotenuse. Thus, the sine of the angular radius of the Sun is ratio of these two distances.
- Parameters:
t (
tuple,list,str,pandas.Timestamp,pandas.Series,pandas.DatetimeIndex,datetime.datetime,datetime.date,numpy.datetime64,numpy.ndarray,astropy.time.Time) – Time to use in a parse-time-compatible format
