Constellation near Carina

Answer 1

The brightest star in the constellation Libra as seen from earth is Beta Librae or Zubeneschamali. It is a blue dwarf star about 160 light years from Earth with a surface temperature of 12,000 Kelvin it is about 130 times as luminous as the Sun.

Answer 2

The brightest star in a constellation is usually called "Alpha", the second-brightest "Beta" (followed by the name of the constellation, for example, "Beta Virginis"). Many of the brighter stars also have their own names; for example, Alpha Canis Mayoris is known as "Sirius".

Answer 3

For an observer on Earth the Sun is the brightest star.

After the Sun (and excluding the Moon and planets) the brightest objects are stars. The 10 brightest (still from an Earth viewpoint) are:

1. Sirius
2. Canopus
3. Rigil Kentaurus
4. Arcturus
5. Vega
6. Capella
7. Rigel
8. Procyon
9. Achernar
10. Betelgeuse

While Sirius (apparent magnitude -1,46) , star #1 in the list above, is about 25 times as luminous (absolute magnitude) as our Sun ; Achernar (apparent magnitude 0,50) , #9, is 3300 times brighter. Canopus is 12900 times as bright. Deneb which did not make the list above (being at #19) is a very visible star from Earth (apparent magnitude 1,25) and 54000 times as luminous as our own Sun (apparent magnitude -26.74) .

Note: if the apparent magnitude is low then the brightness is great.

ACCORDING TO SPACE.COM - IT IS CAPELLA.

BUT THE NY TIMES CROSSWORD PUZZLE CALLED "AHEAD OF THE CURVE" SAYS RIGEL. SO I THINK ELIZABETH GORSKI ,WHO CREATED THE CROSSWORD PUZZLE TODAY , IS WRONG.

Answer 5

Notable Stars in AquariusAlpha Aquarii (Sadalmelik) - A giant star with a diameter perhaps 100 times that of the Sun. It is located 760 light years from Earth and shines at magnitude 2.95.

Beta Aquarii (Sadalsund) - The brightest star of the constellation, shining at magnitude 2.9. Its computed distance is about 600 light years from Earth.

Gamma Aquarii (Sadachbia) - A spectroscopic binary with a period of 58.1 days. It is located 158 light years from Earth and shines at magnitude 3.8. These figures lead to an actual luminosity of about 25 suns.

Maybe you noticed that the three stars described above share similar names. Their Arabic names translate into "The luck of the king", "The luck of lucks", and "The lucky star of hidden things". The origin of the names is quite lost to history, but the next time you wish on a star choose one of these three. You might have a better chance for your wish to come true...

Zeta Aquarii - Zeta is the central star of the of the Y-shaped asterism that makes up the water jar of Aquarius. It is a close pair of 4th-magnitude stars 1.7 arcseconds apart.

R Aquarii - An interesting variable star that reaches the 6th magnitude at maximum and has a period of little over a year. R Aquarii is a symbiotic star system, an interacting pair consisting of a variable red giant and a white dwarf companion.

Answer 7

There are enough exceptions to the rule to make this a somewhat dodgy answer, but if you absolutely have to guess it's probably "eta genitive-name-of-constellation" (Eta Scorpii, Eta Carinae, etc.)

Answer 8

Rigel is the 6th brightest star discovered so far.

Answer 9

Alpha Arietis (Hamal and El Nath), is the brightest star in the constellation Aries.

Answer 10

Canopus is the brightest star in the southern constellation of Carina
