Why does Rigel shine as bright as Betelgeuse even though Rigel is much smaller than Betelgeuse?
Rigel appears as bright as Betelgeuse because it is hotter and more luminous, even though it is smaller. The luminosity of a star depends on both its temperature and size, so a hotter, more luminous star can shine as brightly as a larger, cooler star.
Why does rigel shine as brightly as betelgeuse even though rigel is much smaller than betelgeuse?
Rigel appears as bright as Betelgeuse because it is closer to Earth than Betelgeuse, even though Rigel is smaller and less luminous. The brightness of a star is determined by both its luminosity and distance from Earth, so a smaller, closer star can appear just as bright as a larger, more distant one.
Is Vega or Betelgeuse the brightest star?
Brightness is a function of a stars luminosity as observed from Earth. So our Sun is the brightest. Vega has an apparent magnitude of: 0.03 Betelgeuse has an apparent magnitude of 0.42 So, in apparent magnitude, Vega is brighter.
When can you see betelgeuse on earth?
Betelgeuse is in the constellation Orion and is best seen during the winter months in the northern hemisphere. It is very well placed for viewing around the months of November, December and January. Orion is a very easy constellation to find and Betelgeuse is the very bright and reddish looking star at the top left of it.
What is the name of the brightest star in the constellation Orion, often referred to as the "brightest star in a constellation"?
Ah, what a delightful question you have there, my friend. The brightest star in the constellation Orion is called Betelgeuse. It's like a beautiful beacon shining brightly in the night sky, bringing warmth and wonder to all who gaze upon it. The universe is full of such magnificent stars, each with its own special sparkle to light up our world.
How can Betelgeuse look so bright if it is far away?
It is the brightest type of star, Red Supergiant.
Why can we see betelgeuse so well?
It's very bright.
What does a person from betelgeuse look like?
Betelgeuse is a star, so there is little chance that anyone lives on it.

Betelgeuse is the brightest star in the constellation Orion However Betelgeuse is a cool red star that is 520 light years from Earth How can Betelgeuse look so bright if it is that far away?
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.

Orion is a very easy constellation to find and Betelgeuse is the very bright and reddish looking star at the top left of it.
How can betelgeuse look sso bright if it is far away and has a cool surface?
Several things to consider:-- Because of its ENORMOUS size. We believe that Betelgeuse is about as largeas the orbits of the Asteroid Belt. So if Betelgeuse sat exactly where the sun sits,then Mercury, Venus, the Earth, and Mars would all be inside of it.-- Because it's so close to us. Betelgeuse is roughly 800 light-years from us. That'san enormous distance, but actually pretty close as stars go.-- Because it's so hot. The surface temperature of Betelgeuse is estimated at 3,600 K,which is roughly 3,325° Celsius and 5,960° Fahrenheit. That's pretty cool for a star,but you still wouldn't want to touch it.

Why does Rigel shine just as brightly as Betelgeuse?
Rigel appears as bright as Betelgeuse even though it is further away because Rigel is intrinsically brighter (has a higher luminosity) than Betelgeuse. Despite being further away, its higher luminosity compensates for the distance, making it appear similarly bright in the sky.
Which star is brighter Betelgeuse or Rigel?
Rigel is brighter than Betelgeuse. Rigel is a blue supergiant star and one of the brightest stars in the night sky, while Betelgeuse is a red supergiant and although it is one of the largest stars known, it is not as bright as Rigel.
