Question about colour of stars and planets.

In summary, the sun appears yellow because it is made of white light and blue, green, and indigo light gets scattered. However, the planets and the moon appear white because when you look at them above 25 degrees up in the sky, they do not have a noticeable color change due to scattering. Therefore, they appear white despite being made of the same elements that make the sun appear yellow.

The sun appears white if you look at it about 25 degrees or more up in the sky. Below that the Sun, Moon, Planets, and Stars have noticeable color change due to scattering of the shorter wavelength light.
 

FAQ: Question about colour of stars and planets.

What determines the color of a star?

The color of a star is determined by its surface temperature. Hotter stars appear more blue or white, while cooler stars appear more red or orange.

Why are some planets different colors?

The color of a planet can be influenced by many factors, such as its chemical composition, atmosphere, and surface features. For example, a planet with a lot of iron oxide in its atmosphere may appear reddish, while a planet with a thick layer of methane may appear bluish.

Can the color of a star or planet change?

Yes, the color of a star or planet can change over time due to various factors such as aging, changes in atmospheric conditions, or interactions with other objects in its environment.

Are all stars and planets the same color?

No, stars and planets can come in a wide range of colors depending on their unique characteristics and environments. Some stars may appear yellow, while others may appear purple. Similarly, some planets may be green, while others may be brown.

Do all stars and planets emit their own light?

No, not all stars and planets emit their own light. Stars produce light through nuclear fusion in their cores, while planets reflect light from their nearby star. Some planets, such as gas giants, may also emit a small amount of light due to their own internal heat sources.
