There are millions if not billions of stars in our galaxy, and the Sun is not the hottest or largest in comparison, but in our solar system, it is! Many students have the misconception that because our star is the brightest that we can see, it must be the largest, hottest, and brightest of all stars. Even the next closest star is more than a quarter of a million times farther from Earth, so it is not surprising that the light from the Sun overwhelms that from other stars." Due to the Earth's close (in relative terms) proximity to the Sun, it appears brightest to use because it is closer than all other stars in the galaxy. Although it is a rather typical star, not all that different from many of the ones you see at night, we live so close to it that it outshines everything else. NASA provides some background on the Sun compared to other stars, "Of course, the star that appears the brightest to all of us on Earth is the Sun. If Deneb were the same distance from Earth as Vega, another star in the Summer Triangle, not only would it outshine all the stars and planets visible at night, but it would even be bright enough to see in the daytime!" But Deneb is much farther from Earth than most of the other stars you see, and this giant is around 100,000 times brighter than the Sun. While Deneb shines the brightest in the constellation Cygnus, 17 other stars glow brighter in our night skies. Deneb is northeastern of the three stars that form a large and easily seen grouping called the Summer Triangle. You can see one of them any clear night this summer. "The Sun is the brightest star in the galaxy and no other star can compare." She provides this evidence from NASA to support her argument, "Although we don't know which star truly is the brightest, we know some are remarkably bright. Which piece of text evidence supports the claim that it is possible to measure the actual brightness of stars?ĭot makes a statement to her teacher. Without a good way to know how much of this interstellar fog is blocking the light, there is no reliable way to discover the true brightness of a star." Although it is not the same as the fog on Earth, gas and dust in space can dim the light of stars. Making it still harder to know how bright a star is, there is a kind of patchy fog between the stars - space is not truly empty. The more distant stars are just so fantastically far from us that measuring their distances accurately is too difficult. Although there are some very clever ways of gauging the distances to stars, they generally work well only for stars that are in the Sun's neighborhood of the Milky Way galaxy.

NASA gives background information on the brightness of stars, "To find out the true brightness of a star scientists need to know how far it is. Which student's argument is supported by the teacher's research? Even the next closest star is more than a quarter of a million times farther from Earth, so it is not surprising that the light from the Sun overwhelms that from other stars." Their teacher shares the following information from NASA, "Of course, the star that appears the brightest to all of us on Earth is the Sun. Phoebe: "I have seen brighter stars than the Sun it isn't that great.".Hansel: "The Sun is the brightest star when looking from Earth because it is the hottest.".Gretel: "The Sun appears to be the brightest star because it is the closest to Earth.".Ursula: "The star that appears brightest to us is the Sun because it is the largest in the galaxy.".Four students are making claims about stars and their apparent brightness.
