S Scuti is a carbon star located in the constellation Scutum. Parallax measurements by Hipparcos put it at a distance of approximately 1,300 light-years (390 parsecs). [2] Its apparent magnitude is 6.80, [3] making it not quite bright enough to be seen with the naked eye.
S Scuti is a semiregular variable star. Its class is SRb, and its pulsation cycle lasts 148 days. [4] S Scuti is also surrounded by a roughly spherical shell of dust. The shell was known earlier from its carbon monoxide emission lines. [6] The total mass of the dust is (7 ± 2)×10−5 M☉. [6]
