usually blue, but some are purple-ish like.
The blue giant is blue because of the temperature of the gases surrounding the star. These stars are extremely hot.
Orion is a constellation consisting of many different stars. Orion doesn't have a "color" of its own. The two major stars are the red giant Betelgeuse, and the blue-white supergiant Rigel. The other stars are a variety of colors.
Rigel is actually a triple star system. Rigel A is a blue-white super-giant; the other two are blue-white main sequence stars.
False. Blue giants(or hypergiants) are hotter than Red giant stars. White dwarves are also hotter but they are smaller than blue giants. (As is implied by the name.)
A massive blue giant is a type of star that is very large, hot, and luminous, with a blue-white color. These stars are much more massive than our sun and are in a later stage of their evolution, burning through their fuel at a rapid rate. They typically have short lifespans compared to smaller stars like the sun.
No, blue is not the brightest color of stars. The brightest stars often appear white or yellow in color. The color of a star is determined by its temperature, with the hottest stars emitting blue light.
blue stars are hotter
Yes, Rigel is a blue supergiant star located in the constellation Orion. It is one of the brightest stars in the night sky and is known for its blue-white color and high luminosity.
White Dwarves and Blue giants are both hotter than Red giant stars.
The star FuruD is classified as a red giant, so it appears reddish in color. This is because of its relatively cool surface temperature compared to other stars.
Blue stars are more luminous than other main sequence stars but not necessarily brighter than giant and supergiant stars.
Red stars have the coolest surface temperature. Blue color stars have the highest surface temperature. The Sun belongs to the main sequence stars.
