About Sagittarius Dwarf Spheroidal Galaxy
Sagittarius Dwarf Spheroidal Galaxy is about 85,779 light-years from the Sun, so the light we see from it left about 85,779 years ago.
It is 60,162 light-years from the centre of the Milky Way.
The map lists it as a dwarf galaxy and shows it at the scale of the Milky Way and the Local Group, drawn on the plane of the Milky Way.
A dwarf galaxy on the far side of the Galactic centre, being torn apart by the Milky Way; its stream of stars wraps around the sky twice. Its nucleus is the globular cluster M54.

From Wikipedia
The Sagittarius Dwarf Spheroidal Galaxy, also known as the Sagittarius Dwarf Elliptical Galaxy, is an elliptical loop-shaped satellite galaxy of the Milky Way. It contains four globular clusters in its main body, with the brightest of them — NGC 6715 (M54) — known well before the discovery of the galaxy itself in 1994.
