caption_attribution_description: English: A map of star density in the Milky Way and surrounding sky, clearly showing the Milky Way, large and small Magellanic Clouds, and if you look more closely, NGC 104 to the left of the SMC, NGC 6205 slightly above and to the left of the galactic core, and NGC 7078 slightly below.
context_page_description: The Gaia Sausage is the remains of a dwarf galaxy, the Sausage Galaxy, or Gaia-Enceladus-Sausage, or Gaia-Enceladus, that merged with the Milky Way about 8–11 billion years ago. At least eight globular clusters were added to the Milky Way along with 50 billion solar masses of stars, gas and dark matter.
  The “Gaia Sausage” is so-called because of the characteristic sausage shape of the population in velocity space, a plot of radial versus proper motions of stars measured in the Gaia Mission. The stars that have merged with the Milky Way have orbits that are highly elongated. The outermost points of their orbits are around 20 kiloparsecs from the galactic centre at what is called the “halo break”. These stars had previously been seen in Hipparcos data and identified as originаting from an accreted galaxy.
