Size comparison

The comparison view places selected objects side by side. Text values remain rounded. A minimum display size prevents the smallest objects from disappearing.

Selection

All catalogue identifiers are included by default. You can remove or restore an object, clear the full selection or select everything again.

Black holes

Black-hole masses are labelled separately from diameters. Tests verify that each localized mass label remains present. Do not interpret these badges as a physical diameter at the scene’s scale.

Phoenix A remains a highly uncertain candidate. Treat it accordingly.
