Scutum is not a bright constellation, with the brightest star, [[Alpha Scuti]], being a K-type giant star<ref name=Keenan1989>{{cite journal | bibcode=1989ApJS...71..245K | doi=10.1086/191373| title=The Perkins catalog of revised MK types for the cooler stars| journal=The Astrophysical Journal Supplement Series| volume=71| pages=245| year=1989| last1=Keenan| first1=Philip C.| last2=McNeil| first2=Raymond C.}}</ref> at magnitude 3.85. However, some stars are notable in the constellation. [[Beta Scuti]] is the second brightest at magnitude 4.22, followed by [[Delta Scuti]] at magnitude 4.72. It is also known as 6 Aquilae.<ref>{{cite journal
