There are different seasons map of constellations of the different season of the year. But there is more than just the seasons to tell the difference between constellations, the brightness of the stars in the constellation can be used sometimes to tell the difference between each constellation. Some stars look brighter than others in the sky, not all stars are the same. Astronomers use, what they called the apparent magnitude to measure the brightness of the object in the sky. The astronomer that divided the stars into six different magnitudes based on their brightness is the Greek astronomer, named Hipparchus, in the second century B.C, he also numbered the six classes of the stars from 1 to 6. 1 being the brightest through 6 being the brightest. As we come toward the modern days, the most advanced of the technology we have today to be able to measure the brightness of the stars. Modern astronomers have this advanced tool called a photometer. They now use that technology to help tell the brightness between the stars, instead of judging using their eyes. The brightest star of the night is called Sirius. It measure -1.44, the magnitudes range from -26.72 to +31, the brightest star is -26.72 which is the sun, and the faintest objects in space is +31. 1 magnitude is an equivalent to a ratio of about 2.5 of brightness. …show more content…
As for those that do not know, 12 different kinds of constellation makes up the zodiac sign. In the zodiac constellations, there are Leo, Gemini, Taurus, Aries, Pisces, Capricorn, Sagittarius, Libra, Virgo, Scorpio, Aquarius, Cancer. There is a different kind of zodiac signs, that is used all over the world, based on what their beliefs and religion are, their zodiac constellations may be a whole lot different than ours. But this the one that we all know is that one that I just mentioned, it is commonly known in the U.S and is used to. The constellations that are in the zodiac signs are the constellations, that we can look through a telescope each night to see it, it is also arranged in order. Why is that, you might ask. Will the reason why we are able to see them in their arranged order is because the constellations are in a band around the sky that is centering the ecliptic, which is the path of the Sun that is against that background star, such as the zodiac. The Earth revolves around the Sun and when the Earth is orbiting around the Sun is also crosses the Sun's ecliptic pathway. The zodiac is a band of 12 constellations that circles the sun, and as the Earth is orbiting the sun, we are able to see each and one of the constellations in the zodiac. Each month we are able to see one of the zodiac constellations since there are 12 constellations, it is equally broken up to 1 a month for 12 of
