 Sculptor dwarf is a dwarf scuroidal galaxy. These are very common. They contain an old stellar population with large separations between stars. They are also devoid of gas and dust, so there is no new star formation. A team of astronomers use data from both the Hubble Space Telescope and the Gaia satellite to directly measure the 3D motions of individual stars in sculptor. Their results show that the galaxy's orbit is quite elongated. Currently at 290,000 light-years, Sculptor dwarf is near to its closest point to the Milky Way, but its orbit will take it as far out as 725,000 light-years.
