| Carina | 2.4 | 91 | −38 | [1] |
| Sextans | r0 = 85 | [2] | ||
| Sculptor | 5.4 | 9.9 | −86 | [1] |
| Fornax | 39 | 48 | −126 | [1] |
Notes. (X,Y,Z) coordinates correspond to a right-handed coordinate system with an origin located at the centre of the MW. The centre of the of the MW coincides with the X–Y plane, with the present location of the Sun on the positive X axis. Sextans is listed only at the current-day radial distance r0. As the MW is treated as a spherical object in this paper, this has no effect on any results.
