Does anyone have information on the constellation Casseiopeia?

Question

temperature, size, color of stars alpha beta gamma and delta would be what i am looking for.

Answer 1

Cassiopeia (only one e) forms a distinctive W-shape asterism which is easily recognised in the skies.

The four brightest stars are all 2nd magnitude:

Tsih; γ Cassiopeia: Magnitude: 2.15. Distance 613 light years. Stellar classification: B0 IV: evar prototype of the γ Cas variables.

The apparent magnitude of this star was +2.2 in 1937, +3.4 in 1940, +2.9 in 1949, +2.7 in 1965 and now it is +2.15. At maximum intensity, γ Cassiopeiae outshines both α Cassiopeiae and β Cassiopeiae.

Schedar: α Cassiopeia: Magnitude: 2.24. Distance 229 ± 9 light years. Stellar classification: K0 II-III var (giant).

Caph: β Cassiopeia: Magnitude: 2.28. Distance 47 ± 4 light years. Stellar classification: F2 III-IV (giant). δ Scuti variable. Its brightness varies from magnitude +2.25 to +2.31 with a period of 2.5 hours

Ruchbah: δ Cassiopeia: Magnitude: 2.66. Distance 99.4 ± 1.9 light years. Stellar classification: A5 Vv SB eclipsing binary. Its magnitude varies between +2.68 mag and +2.74 with a period of 759 days

TSIH: As a B0 star it is blue, with a photospheric temperature of 25,000 K and is perhaps 7 Solar diameters in size.

SCHEDAR: As a K0 star it is orange, with a photospheric temperature of 4,530 K and is about 42 Solar diameters in size.

CAPH: As a F2 star it is yellow, with a photospheric temperature of about 6,700 K and is about 4 Solar diameters in size.

RUCHBAH: As an A5 star it is white, with a photospheric temperature of 8,000 K and is about 2.1 Solar diameters in size.

Cassiopeia contains two stars visible to the naked eye that rank among the most luminous in the galaxy: ρ Cas and V509 Cas. The star η Cas is a nearby (19.4 ly) binary star comprising of a yellow Sun-like dwarf and an orange dwarf star.

If we were to observe Earth's Sun from Alpha Centauri, it would appear to be in Cassiopeia as a yellow-white 0.5 magnitude star. The famous "W" of Cassiopeia would become a zig-zag pattern with the Sun at the leftmost end, closest to ε Cas.

Answer 2

you should ask the guy Astro whi answers questions in here ! he is an astronomer! he'll know everything you need to know especially the star info.

He helps me out alot!
Really nice he is .

Answer 3

I don't. But if you can figure out how to use a search engine, there are a *bunch* of sites that have lots of information on that constellation.

Answer 4

There are star atlases that tell you that. The constellation is not particularly bright.

Answer 5

the myth was that the queen was chained onto the thingy to be eaten by some sea monster or another. long and complicated. look it up.
