A star's brightness is indicated by a numbercalled its magnitude. It's a reversed scale, so brighter stars have smaller magnitude numbers. Our Sun's magnitude is approximately +5, not especially bright. Letters are used to indicate the surface temperature (and therefore the color) of a star. O, B, and A are very hot blue stars. F are white, G are yellow, K are orange, and M are the red coolest stars visible. Our sun is a G star, yellowish white.
There is no star with the name of "Beta". No, that's not true. To be more correct, there is a "beta" in every constellation. That's a total of 88 of them in the sky ! Within each constellation, the brightest star is labelled "Alpha of (the name of the constellation)", the second brightest is labelled "Beta of (the constellation's name)", the third brightest is labeled "Gamma of (the constellation)" and so on through the constellation. Well, that's the general idea anyway. The system of assigning names to stars got a bit mixed up and for various reasons, "Beta" is not always strictly speaking the second brightest star in a constellation, but for most of them it will at least be one of the brightest stars in the constellation. Also, the "of the constellation" part is in Latin, and forming Latin genitives isn't always straightforward for English speakers (some examples: "of Cephus" -> Cephei, "of Ursa Minor" -> Ursae Minoris, "of Virgo" -> Virginis).
Alpha Librae is the second brightest star in the constellation Libra.It has an absolute magnitude of +3.28It has an apparent magnitude of +5.15
Sirius is the brightest star in the sky. It is in the constellation of Canis Major, visible in the northern hemisphere during the winter months. Canis Major is also known as the Big Dog, earning the star its nickname -- "the Dog Star."
There are no stars in the earth's atmosphere. The brightest star, also the brightest object of any kind, in our sky is the sun. It's about 375,000 times farther from you than the top end of earth's atmosphere is. The moon and several of the planets are all brighter than all the other stars. The second brightest star in the sky ... next after the sun ... is the one called 'Sirius'. It's located about 8.6 light-years from us, which is about 63,000 times farther than the sun.
The 'little dipper', or the constellation of Ursa Minor, the little bear, is not part of the solar system. It consists of stars, like our Sun, which are much further away than any planet, even Pluto. Polaris, the brightest star in the constellation, is 434 light years away. Kochab, the second brightest star is 131 light years away. They, and the other stars of the group, have nothing to do with each other, they just happen to be in the same rough direction as seen from Earth.
Beta (β). The second brightest star is β Lyr (Sheliak).
Zeta Herculis (Rutilicus) is a binary star system in the constellation Hercules.It is the second brightest star in the constellation with an apparent magnitude of +2.89
Beta Aquarii (Sadalsuud) is the brightest, and Alpha Aquarii (Sadalmelik) is the second brightest star in Aquarius.
It is in the Orion constellation, and its about 640 light-years away from Earth. It is the second brightest star in the constellation, and the eighth brightest star in our night sky.
Castor is the second brightest star in the constellation Gemini.
The primary star in a constellation is called the "Alpha" star - it's almost always the brightest one in the constellation. "Beta" is the second brightest, and it follows the Greek Alphabet as the stars get dimmer... Polaris is the North Star located in the constellation Ursa Minor - the Little Bear.
Gamma Virginis or (Porrima and Arich) is the second brightest star in the constellation Virgo with an apparent magnitude of 2.74
Gamma Leonis (γ Leo, γ Leonis) (Algieba or Al Gieba) (a binary star system) is the second brightest star in the constellation Leo.
Betelgeuse, or Alpha Orionis, is a red supergiant and second brightest star in the constellation Orion.
Canopus is located in the constellation of Carina in the southern sky. It is the second brightest star in the night sky, after Sirius.
Betelgeuse is a red supergiant star located in the constellation of Orion. It is one of the brightest stars in the night sky and can be easily seen with the naked eye in the Orion constellation, particularly in the "shoulder" area of the Orion constellation.
Delta Capricorni, or Deneb Algedi has a magnitude of 2.9 and is the brightest. Beta Cap, magnitude 3.1 is second. .
