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).[1] Its apparent magnitude is 6.80,[2] making it not quite bright enough to be seen with the naked eye.

Louisa Dennison Wells discovered that the star is a variable star. Her discovery was announced in 1901.[3] It was listed with its variable star designation, S Scuti, in Annie Jump Cannon's 1907 work Second Catalog of Variable Stars.[4] S Scuti is a semiregular variable star. Its class is SRb, and its pulsation cycle lasts 148 days.[5] 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 Template:Solar mass.[6]
