what type of stars does sagitta have? meaning list the star and tell me if they are red giant and ect. and other thing where can i found a picture of sagitta that have all the stars in it , that belong to sagitta?Can you please help me with my constellation project? it is....?I think we have to assume that if you say Sagitta you mean Sagitta and you do not mean Sagittarius.
Here are the 15 brightest stars in the constellation in descending order of magnitude: the HD numbers are he numbers in the Henry Draper Catalogue, the first serious attempt to record the spectral class of all the stars listed in a major star catalogue.

HD190211 5.99 849 ly K3 Iab
I stopped at Magnitde 6, the limit of naked eye visibility but obviously there are far many more stars below magnitude 6 than above it. The frst link carries on down to magnitude 6.84, with a further 14 stars listed.
To understand the spectral classes quoted you need to read about the Morgan-Keenan spectral classes of stars (see link).
Blue stars are the hottest and in class O and B. Then come classes A, F. and G (our Sun is in Class G) which are white and yellow, followed by K (orange) and M (red).
Size is indicated by the Roman numerals I - VII. The largest stars are size I and our Sun is a dwarf of size V.
The following table may be helpful:
A number of different luminosity classes are distinguished:
I supergiants
Ia-0 (hypergiants or extremely luminous supergiants (later addition), Example: Eta Carinae (spectrum-peculiar)
Ia (luminous supergiants), Example: Deneb (spectrum is A2Ia)
Iab (intermediate luminous supergiants)
Ib (less luminous supergiants), Example: Betelgeuse (spectrum is M2Ib)
II bright giants
IIa, Example: β Scuti (HD 173764) (spectrum is G4 IIa)
IIab Example: HR 8752 (spectrum is G0Iab:)
IIb, Example: HR 6902 (spectrum is G9 IIb)
III normal giants
IIIa, Example: ρ Persei (spectrum is M4 IIIa)
IIIab Example: δ Reticuli (spectrum is M2 IIIab)
IIIb, Example: Pollux (spectrum is K2 IIIb)
IV subgiants
IVa, Example: ε Reticuli (spectrum is K1-2 IVa-III)
IVb, Example: HR 672 A (spectrum is G0.5 IVb)
V main sequence stars (dwarfs)
Va, Example: AD Leonis (spectrum M4Vae)
Vb, Example: 85 Pegasi A (spectrum G5 Vb)
VI subdwarfs (rarely used)
VII white dwarfsCan you please help me with my constellation project? it is....?Sagitta the Arrow is a small constellation and its brightest star has a magnitude of 3.5, not very bright. Do you mean Sagittarius the Archer? Its brightest stars look like a teapot. The Milky Way is very prominent here and there are many clusters and nebulae, including the Trifid and Lagoon. Great constellation to look at through binoculars on a summer evening in the southern sky.Can you please help me with my constellation project? it is....?here are some usefull web sites:
