Which is likely to be colder a night when you can see the stars or a night when you Cannot see?

The night w/ stars will likely be colder than the night w/out stars. A night with stars implies a clear sky i.e., the absence of clouds. The earth’s outgoing long wave radiation is free to escape into space in the absence of clouds which allow the near-surface temperature to fall farther than if the sky was cloudy.

Are there stars hotter than the sun?

The hottest stars have surface temperatures of 50,000 Kelvin degrees. The Sun surface is only 5800 Kelvin degrees, which means that there are hotter starts than the Sun. Answer 3: There are many stars that are hotter than the sun — for instance, stars that burn blue are hotter than our sun!

Why are certain stars hotter than others?

Some stars are much more powerful than others, emitting far more light. And the larger the star, the more square inches of surface, so the more total light it emits into space. A star that’s the same temperature as the Sun but twice its diameter, for example, emits four times more light.

Why you only see stars other than the sun at night?

During the day, the light of the Sun makes our sky so bright that we cannot see the much dimmer stars. At night, in the absence of the Sun, the sky becomes dark and the light of the stars can be seen. That is why, we are able to see the stars clearly only at night.

Which star is hottest?

Blue stars
White stars are hotter than red and yellow. Blue stars are the hottest stars of all. Stars are not really star-shaped. They are round like our sun.

Is lava hotter than fire?

While lava can be as hot as 2200 F, some flames can be much hotter, such as 3600 F or more, while a candle flame can be as low as 1800 F. Lava is hotter than a typical wood or coal-buring fire, but some flames, such as that of an acetylene torch, is hotter than lava.

What makes a star hotter?

In most stars, like our sun, hydrogen is being converted into helium, a process which gives off energy that heats the star. The inside is actually millions of degrees, extremely hot! That warms the outer layers of the star, which gives off heat and light.

Which are the hottest stars?

Blue stars are the hottest stars of all. Stars are not really star-shaped. They are round like our sun. Most stars are so much farther from us that they are not as bright as the sun.

How can we see stars at night?

Even though the stars that we see in the night sky are all very far away, we can see them not by actually being able to resolve their sizes, but by measuring the light that they produce. where F is a measure of the amount of light from the star (called the “flux”) and d is the distance to the star.

How do we see stars in the sky?

Answer: Even though the stars that we see in the night sky are all very far away, we can see them not by actually being able to resolve their sizes, but by measuring the light that they produce.
