The closer a light source is to your eye, the brighter it appears - intensity included. The closer you are to the source, the larger the angle of the cone; your pupil as the base and the source as the point. The larger the angle from the point, the more light entering your eye. Too close to the source and your retinal area becomes the limiting factor.

How light is Uranus?
Elipson is the brightest ring of uranus...
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.
What is the dimmest planet?
Pluto
Which is the brighest planet?
By definition, a planet doesn't produce its own light. So the brightest planets are the ones who reflect the most light back out from surrounding stars. In our solar system i'd take a look at venus, and you could even make the argument of Pluto if you wanna push it. Pluto although not considered a planet anymore, but when it was, is covered in ice. Therefore, reflecting more percent of light than most of our planets if not all, making it the "brightest". But at our distance and rationalization venus would probably be your safest bet on a high school exam.

What is a low beam?
Well, assuming that you are talking about headlights, the low beams are the dimmest settings for the drive headlights, while high beams are the brightest setting.
The D to A C is A 4 L Y?
First a little bit of astronomy... The brightest stars in a constellation are ranked by the letters of the Greek alphabet - so the brightest one is always known as Alpha.... The distance light travels in a year is 1 light year.... There is a constellation called Centaurus.... .... so the answer to the puzzle is.... The Distance to Alpha Centauri is About 4 Light Years.

How many light years are in rastaban?
Rastaban is the second-brightest star in the constellation of Draco. It's estimated to be situated at a distance of about 380 light years from Earth.
What is the brightest planet in the solar system?
venusearthKeep in mind that planets do not emit light. Their brightness depends on the brightness of the light source illuminating them, on their distance from that light source, on their surface albedo, and on their distance from the viewer. Therefore, which planet appears brightest depends on where the viewer is in the solar system. From earth, Venus is the brightest planet both because of the relative distances and its high surface albedo (which is due to its surface being completely covered by very white cloud cover).
What is the dimmest star in pegasus?
