concentric
Rings within rings
Concentric describes circles or other shapes that share the same center point, like the rings of a tree trunk or ripples spreading from a stone dropped in water.
The opposite is eccentric—off-center.
The target had five concentric rings.
The term extends to any arrangement radiating outward from a common center: concentric circles of influence.
