It's actually -1.46 apparent magnitude that is, she just rounded it off, so she is correct.
@luketube83512 жыл бұрын
So many videos on what apparent/absolute magnitude IS, how to USE the numbers on a scale, but no one explains how to FIND those numbers. Where does 0.87 or -0.63 come from ? How do you actually get that number? I know it's to do with filtering light, but I can't find any video that talks about how to get those numbers.
@learnthesky2 жыл бұрын
Magnitude can be a frustrating concept. Many of these numbers were first made by Hipparchus. 1st mag = brightest. 6th mag = dimmest. This system carried on for centuries. Once Galileo started seeing more stars with his telescope, he started naming 7th mag, etc….at this point there is a formula on how to calculate it (mentioned in video), and now we don’t rely on human eyes solely for magnitude. We use telescopes to help determine this. The star Vega is the standard for magnitude zero. I hope this helps. I may need to eventually do a video going into the details of this.

Is there an advantage to having an inverse scale? If not why don't astronomers agree to make it more intuitive?
@clarkg98052 жыл бұрын
Are you saying that they can only measure stars absolute magnitude if they are at 10 parsecs away from earth, or 32.6 light years? Is that figurative or literal? Do you know if there is a reason for that particular distance to be used for this value determination? Sorry don't mean to be difficult, your video's are very informative, thank-you for sharing. : )
@learnthesky2 жыл бұрын
I do not know the reason for why the distance of 10 parsecs (32.6) light years away. I will need to do further digging on that. And this would be a figurative thing. So if you placed the star at 10 parsecs, how bright would it be? I see it as a way to compare stars. Remember that just because a star is bright in our sky, it does not mean it is big, it could just be close. By using absolute magnitude, it allows us to compare a star's size, which is directly related to its brightness. I hope this helps. Magnitude has always been slightly confusing to me, probably because of the inverse scale it has.

Without stellar magnitude.;..with the same distance which is brighter 1st magnitude or 6th magnitude? i thought sixth magnitude is brighter between the two..limited by its brightness because of the distance

Is a magnitude 4 object 10X brighter than a mag 5 ?
@abhilashpradeep69252 жыл бұрын
Madam u said that apparent magnitude tells the brightness of star and absolute magnitude tells the brightness of star which is in certain distance,Suppose if the apparent magnitude of a star is 14.5,then it is brightest or low brightest.
@learnthesky2 жыл бұрын
A star with a magnitude id 14.5 would be a very dim star. It would be invisible to the naked eye.

I don't understand how to read a logarythmic scale, I've been googling but I'm probably too retarded. I want to understand how to calculate how much brighter a magnitude 4 is compared to a 6 for example, how do I calculate this.. I don't get it.
@betaorionis216411 ай бұрын
Logarithmic means that a value 1 unit bigger is x times bigger than the previous unit. You have to multiply by an X factor instead of adding a quantity. In the case of the magnitude of stars, 1 unit of magnitude means approximately 2.5 brighter than the previous magnitude. If you want to compare magnitude 4 to magnitude 6: - magnitude 5 is 2.5 times brighter than magnitude 6 - magnitude 4 is 2.5 times brighter than magnitude 5 - so, magnitude 4 will be 2.5*2.5 = 6.25 times brighter than magnitude 6

No, Venus is not a star, but it looks like one in the sky. The same magnitude system that is used to describe the brightness of the stars is also used for the planets.
