About Stellar halo (break radius)

Stellar halo (break radius) is about 72,910 light-years from the Sun, so the light we see from it left about 72,910 years ago.

It is 88,062 light-years from the centre of the Milky Way.

The map lists it as a galactic structure and shows it at the scale of the Milky Way and the Local Group, drawn on the plane of the Milky Way.

The density of halo stars drops more steeply beyond about 25–30 kpc. Halo stars are traced beyond 100 kpc.
