sci.ecliptic-to-equatorial Calculator
Converts between ecliptic (sun-centred) and equatorial (Earth-centred) celestial coordinate systems using the obliquity of the ecliptic (23.44°). Planets move close to the ecliptic plane — the obliquity of 23.44° causes Earth's seasons by changing the angle of sunlight over the year.
Inputs
Ecliptic Longitude Deg
Reference formula or conversion factor shown for context.
Ecliptic Latitude Deg
Reference formula or conversion factor shown for context.
Obliquity Deg
Reference formula or conversion factor shown for context.
Results
right ascension RA (°)
Sample size or count used in the calculation.
RA (hours)
The result expressed in hours. Divide by 24 to convert to days.
declination Dec (°)
The value at the specified point or condition.
ecliptic longitude lambda
Sample size or count used in the calculation.
obliquity of ecliptic
Reference formula or conversion factor shown for context.
