Because of its ENORMOUS size. We believe that Betelgeuse is about as large as a the orbits of the Asteroid Belt, so if Betelgeuse were here in our own solar system, it would consume Mercury, Venus, Earth and Mars, and probably destroy Jupiter as well.
As stars go, the 800 light-year distance to Betelgeuse is not that far away, although we wouldn't want it to be any closer. When Betelgeuse becomes a supernova, it will likely outshine the Moon.
The answer can only be that you do not live within the tropics (the Tropic of Capricorn and the Tropic of Cancer), or if you do, you are puzzled because the sun is not always at your zenith. If there were no tilt at all to the earth's axis, then the sun would reach the zenith every day, at every point of the equator. The earth's equatorial plane and the ecliptic would be coplanar. The equator would be the only place where the sun exactly reaches zenith. Since there is a tilt of very close to 23.5 degrees, the sun exactly reaches zenith at the equator two times per year, and it will reach zenith at the tropics once each during a year.
Due to it's enormous energy output, the distance doesn't make a lot of difference.
Compare a candle three feet in front of you, versus an atomic bomb going off three miles away. The second will be much brighter than the first.
It's not. The distance between the sun and the earth is constant and does not stay the same. If the distance between the two bodies changed significantly, the earth would either burn up when it got closer to the sun, or freeze when it went farther away from the sun.
Because the sun light has nothing to reflect off of. The only way to see sun shine is when it is reflected off something.
Such stars often have a very large surface area. This will more than compensate for the reduced power output per square meter.
Because your an idiot!
Because It's a star.
A supergiant star has an atmosphere that extends far from the star's center. On a surface area basis, square meters say, the surface is very dim. But since the size is so great the overall brightness is high. Betelgeuse is a good example. The outer atmosphere is so tenuous that there is actually a star orbiting within it. But it is so large that it shines brightly at the right shoulder of Orion.
High
Here are a few:T Cephei, VV Cephei, VY Canis Majoris, NML Cygni, WOH G64, and V059 Cassiopae. ... Mu Cephei, Mu Cephei A, ... There are certainly an extremely high number of stars that are bigger than Betelgeuse in the known universe alone.
the high power objective lends is bigger do that it feels like a d
Magnitude is a measure of brightness, there is no relationship with density.
Because it's huge ! It's a supergiant! Hence the word SUPER!
The red giants like Betelgeuse and Antares are bright and - relatively - cool.

Yes, it will. The higher the brightness. the less the battery life will be.
Proxima Centauri has an insignificant luminosity to Betelgeuse. Although it is the closest known star(4.2 light-years) to our Sun, it is virtually impossible to see because it is so dim. Betelgeuse, on the other hand, is a lot farther (640 light-years). Yet, it is one of the brightest stars in our night sky. This is because Betelgeuse has an extremely high luminosity.
Betelgeuse is the eighth brightest star in the night sky and the second brightest star in the constellation of Orin. It is classified as a Red Giant. Astronomers believe that Betelgeuse is only 10 million years old, but has evolved rapidly due to its high mass. Betelgeuse is made from: Helium, Carbon, and Oxygen. Astronomers don't know when but they are sure that Betelgeuse will explode and become a SuperNova. Betelgeuse is 700 million miles in diameter and the surface temperature is 6,000 degrees Fahrenheit. Its luminosity is about 10,000 times the Sun and it's the first star to be directly imaged by a telescope. Finally Betelgeuse is visible in winter skies from the Northern Hemisphere in the constellation Orion. Hope that Helped You :)

Hi beam lights only the High brightness filament of the headlight.Lo beam lights only the Low brightness filament of the headlight.DRL lights only the High brightness filament of the headlight, but at reduced current.Do you see the pattern?
Ray Bans come in 5 categories. 0 is for use in "dimmed brightness" (cloudy conditions). 1 is for partly sunny. 2 is for medium brightness. 3 is for high brightness. 4 is for exceptional brightness. However, category 4 glasses are not recommended when driving. There are three letter codes. N-normal. P=Polarizing. F=photochromatic. Hence 3n means normal, for high brightness.
Betelgeuse ("beetlejuice") is believed to be only a few million years old (~ 8.5 million) due to it's high mass. It is also believed, that it may become a supernova within a time frame where it could be observed by human civilization.
How high it is tells you its intrinsic brightness (i.e. its brightness after allowing for distance). How far to the left it is tells you how hot it is at the surface.
