moved on from the asymptotic giant branch of stellar evolution and is on its way to becoming a planetary nebula. FG Sagittae is a "born again" star, a highly luminous star around distant from Earth. It reignited fusion of a helium shell shortly before becoming a white dwarf, and has expanded first to a blue supergiant and then to a K-class supergiant in less than 100 years. It is surrounded by a faint (visual magnitude 23) planetary nebula, Henize 1–5, that formed when FG Sagittae first left the asymptotic giant branch. S Sagittae is a classical Cepheid that varies from magnitude 5.24 to 6.04 every 8.38 days. It is a yellow-white supergiant that pulsates between spectral types F6 Ib and G5 Ib. Around 6 or 7 times as massive and 3,500 times as luminous as the Sun, it is located around from Earth. HD 183143 is a remote highly luminous star around away, that has been classified as a blue hypergiant. Infrared bands of ionised buckminsterfullerene molecules have also been found in its spectrum. WR 124 is a Wolf-Rayet star moving at great speed surrounded by a nebula of ejected gas. U Sagittae is an eclipsing binary that varies between magnitudes 6.6 and 9.2 over 3.4 days, making it a suitable target for enthusiasts with small telescopes. There are two component stars—a blue-white star of spectral type B8 V and an ageing star that has cooled and expanded into a yellow subgiant of spectral type G4 III-IV. They orbit each other close enough that the cooler subgiant has filled its Roche lobe and is passing material to the hotter star, and hence it is a semidetached binary system. The system is distant. Near U Sagittae is X Sagittae, a semiregular variable ranging between magnitudes 7.9 and 8.4 over 196 days. A carbon star, X Sagittae has a surface temperature of . Located near 18 Sagittae is V Sagittae, the prototype of the V Sagittae variables, cataclysmic variables that are also super soft X-ray sources. It is expected to become a luminous red nova when the two stars merge around the year 2083, and briefly become the most luminous star in the Milky Way and one of the brightest stars in our sky. WZ Sagittae is another cataclysmic variable, composed of a white dwarf that has about 85% the mass of the Sun, and low-mass star companion that has been calculated
