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:
- Create the study from the Ephemerides menu or the toolbar. See Create Study.
- Configure its basic settings and date range, then choose the bodies and metrics to include.
- Click the Run button to generate the records.
- 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.
