Heliocentric Ephemeris Study

A heliocentric ephemeris study generates a table of heliocentric (Sun-centered) planetary positions at fixed time intervals over a date range. Its coordinate origin is fixed to heliocentric. Like the other study types, it uses the shared configuration, generation, and results surfaces.

Working with a Heliocentric Study

To create and generate a heliocentric study:

  1. Create the study from the Ephemerides menu or the toolbar. See Create Study.
  2. Configure its basic settings and date range, then choose the bodies and metrics to include.
  3. Click the Run button to generate the records.
  4. Review the results in the ephemeris table, then export them to CSV if you need them elsewhere.

Because a heliocentric study is centered on the Sun, its body list differs from the Earth-centered studies: the Sun, Moon, and lunar points do not apply, and Earth is included instead. For the complete list, see Bodies Selection List.
