A star is surrounded by a nebula formed by matter ejected 0.4–1.2 pc from the star. The nebula contains about 15 solar masses, all of which are hardened to be lost from the star 10,000 years ago. The interstellar medium around the star has an empty chamber 8.8 pc wide, which is formed by the stellar wind that is emitted at the star ‘s initial points
