The Teapot is largely composed from the stars of two smaller asterisms. Its handle and lid are formed from the five stars of the Milk Dipper, while the bow of Sagittarius runs down the western side of the Teapot from its lid. Together, these two asterisms account for seven of the eight stars of the Teapot. The eighth star, Alnasl, represents the end of the Teapot's westward-pointing spout.
The shape of the Teapot in the skies of Earth is purely a line-of-sight effect. The eight stars that make up the shape are actually quite unrelated to one other, and widely separated in space. They range from Kaus Borealis (marking the Teapot's 'lid') some 78 light years from Earth, to Kaus Media, appearing close to Kaus Borealis in the sky but actually more than four times farther from the Solar System.
The Teapot occupies an area in the general direction of the Milky Way'score, and so the eight stars that make it up lie against a rich backdrop. This is especially true of globular clusters, of which three important examples - M54, M69 and M70 - lie within the Teapot itself. Another two prominent clusters of the same kind - M22 and M28 - fall outside the Teapot shape itself, but nonetheless lie close to the 'lid' of the formation.
