What does this calculator do?
A stellium is a concentration of multiple planets in one zodiac sign or house under a stated rule. This calculator identifies qualifying groups and shows which definition it applies.
This page separates astronomical or arithmetic calculation from interpretation. It reports only values supported by the supplied data and the selected calculation method. Missing information is shown as unavailable rather than replaced with a guessed value.
Results included
- Sign-based stelliums
- House-based stelliums when available
- Included planets
- Defined minimum planet count
- Degrees and spread
How to read the technical result
Check the sign or number first, then review exact degrees, houses, aspects, or reduction steps where they apply. A complete result should identify the input data, calculation system and any limitations. These details make the result reproducible and easier to compare with other professional tools.
Accuracy and data limitations
Without birth time, sign-based groups can still be checked, but house-based stelliums must be omitted. Names, dates, local times and locations should be entered carefully. A technically correct calculator cannot recover information that was not supplied, and Moodfex does not manufacture missing birth data.

Can I have a house stellium without birth time?
No. Reliable houses require an accurate birth time.
Is every group of planets a stellium?
