What is the bright star in the West?
Venus is so bright because its thick clouds reflect most of the sunlight that reaches it (about 70\%) back into space, and because it is the closest planet to Earth. Venus can often be seen within a few hours after sunset or before sunrise as the brightest object in the sky (other than the moon).
Why is the star shining so bright?
Stars shine because they are extremely hot (which is why fire gives off light — because it is hot). The source of their energy is nuclear reactions going on deep inside the stars. In most stars, like our sun, hydrogen is being converted into helium, a process which gives off energy that heats the star.
Why is Venus so bright right now?
Bottom line: Venus is the third-brightest object in the sky, after the sun and moon. That’s partly because sunlight is easily reflected by acidic clouds in the atmosphere of Venus.
Can you see Venus right now?
Because Venus is so, so bright. Just look west after sunset in December 2021. From that evening through at least the evening of December 9, you can see spectacularly beautiful scenes in the sky after sunset, as the moon sweeps up away from the sun in our sky, passing first Venus, then Saturn, then Jupiter.
Do stars shine or reflect?
A star shines or glows because its gravity causes its gases to fuse together. This process releases energy, hence the “shine”. Part of this confusion was because while all sky objects appear bright, some stars and galaxies (collections of stars) radiate light, while the others only reflect light.
Is Venus visible every night?
Venus is always the third-brightest object in the sky behind the sun and the moon, and it’s always brighter than the brightest stars. However, because it orbits relatively close to the sun, it’s only ever visible for a short time after sunset or before sunrise.

Are brighter stars hotter?
Explanation: Bright main sequence stars tend to be larger and hotter. Some of the brightest stars, such as Sirius and Rigel have surface temperatures of 10,000K or more. Betelgeuse on the other hand is a bright red giant with a surface temperature of less than 4,000K.
Are stars brighter than the sun?
Every star you see in the night sky is bigger and brighter than our sun. Of the 5,000 or so stars brighter than magnitude 6, only a handful of very faint stars are approximately the same size and brightness of our sun and the rest are all bigger and brighter.
Why do some stars appear brighter than others?
A star’s brightness also depends on its proximity to us. The more distant an object is, the dimmer it appears. Therefore, if two stars have the same level of brightness, but one is farther away, the closer star will appear brighter than the more distant star – even though they are equally bright!
