STAR
Every visible star is an example of emitted light, regardless of how bright it seems. Several invisible ones are too, even though there are external reasons why they're invisible to us.
The North Star currently refers to Polaris, an F7 Supergiant approximately 433 light years from Earth.
Because it is bright but more importantly, it is relatively close to Earth - a mere 8.6 light years from us, which is close in star terms.
It isn't the brightest star - at least, usually Rigel is brighter. However, Betelgeuse is variable, and can sometimes be brighter than Rigel. Wikipedia lists its luminosity as 105,000 times the luminosity of our Sun; and the distance, as 640 light years. Assuming these numbers, this would make it as bright as a star that is 10.5 times as bright as our Sun, at a distance of only 6.4 light years. In other words, the extreme luminosity compensates for its distance.
Yes, it is.

If you already know how to play twinkle twinkle little star on the recorder, It's just the same notes. :-)

Marking the moment is when there is an individual part in the play that is very important. Like if someone is in the spot light with cameras and bright lights all around them just making them a star
Venus is the brightest star. It is also the hottest planet it reflects a lot of light from the sun and we can see it as a bright dot in the sky.
Star brightness is defined in terms of apparent magnitude, which is how bright the star appears from Earth. Star brightness is also defined by absolute magnitude, which is how bright a star appears at the standard distance of 36.2 light years. Luminosity is also a way that a star's light is measured.
