Your birth chart
Find your sign stelliums
Check for groups of 3 or more bodies in one zodiac sign. See which bodies are included and whether the group changes with an uncertain birth time.
Astriel counts the Sun and Moon alongside the planets Mercury through Pluto. An unknown birth time works too.
How the count works
Suppose the Sun, Mercury, and Venus are in Taurus. That is a 3-body sign stellium under Astriel's rule.
Adding the North Node in Taurus does not raise the count. Adding Mars does: the group then has 4 bodies.
This example is a counting exercise, not a calculated chart for a particular date.
Read the planets inside the group
A sign stellium concentrates several planetary functions in the same sign. With Sun, Mercury and Venus in Taurus, purpose, thinking and preference all use Taurus themes of continuity and tangible value.
Each planet still has its own role. Mercury describes how information is handled; Venus describes what is valued. Replacing Venus with Mars changes the interpretation because initiative takes the place of preference, even though the count stays at three.
Astriel uses a stated counting rule. Other astrologers require four bodies or a chain of conjunctions, so two tools can disagree about the label while showing the same positions.
Sharing a sign and forming a conjunction
A sign spans 30 degrees. Two bodies can share that sign while remaining too far apart to form a conjunction under our orb limits.
Astriel counts sign membership here. Use the full birth chart to inspect the angular contacts between those bodies. The aspect guide explains the limits.
If the birth time is unknown
We check the local calendar day at the birthplace. With an approximate time, we check the selected period.
A body can move to another sign during that period. The result separates each possible membership and labels groups that stay the same throughout the checked range.
For example, a group with the Sun, Mercury, and Venus can gain the Moon later in the day. Those are two possible memberships of one sign group.
What a stellium count can tell you
The count identifies a concentration of bodies in one sign under this method. It does not rank your chart or establish a dominant planet.
The result links to a sign guide for context. A personal interpretation needs the wider chart, including the individual bodies and their aspects.
This tool checks sign groups. House groups and a rule requiring every member to form a conjunction are separate calculations.
