- How is the star Betelgeuse different from the sun? Betelgeuse is a supergiant red star that is nearing its end of life. The sun is a relatively small main sequence star in the middle of its life. It is believed that Betelgeu … se is only 10 million years old, and that it has evolved so rapidly because of its extremely high mass - it is one of the largest stars we know of - and its demise as a type II supernova is predicted within only the next 1 million years.

Betelgeuse Astronomers now know that these regular brightness variations are caused by changes in the actual size of the star's atmosphere. According to Robert Burnham, Jr. (1931-93), Betelgeuse is the only marked variable among the first magnitude stars as well as the 11th brightest star in the sky.

Big Fat Star Betelgeuse Sheds Pounds Like Crazy Published July 29, 2009. As a large star nears the end of its life it begins to shed mass at a tremendous rate. New observations of the supergiant star Betelgeuse may help scientists finally understand how this feat of weight loss is achieved. Views from the European Southern Observatory's Very Large Telescope in Chile reveal a vast plume of gas spewing off of Betelgeuse, the shoulder star in the Orion constellation.

Betelgeuse Betelgeuse Betelgeuse is the brightest star in Orion and marks the western shoulder of the constellation. Betelgeuse is one of the largest known stars and is probably at least the size of the orbits of Mars or Jupiter around the sun. That's a diameter about 700 times the size of the Sun or 600 million miles.

Star Colors and Temperatures Cool stars (i.e., Spectral Type K and M) radiate most of their energy in the red and infrared region of the electromagnetic spectrum and thus appear red, while hot stars (i.e., Spectral Type O and B) emit mostly at blue and ultra-violet wavelengths, making them appear blue or white.

- Blue stars are stars that have at least 3 times the mass of the Sun and up. Whether a star has 10 times the mass of the Sun or 150 solar masses, it’s going to appear blue to our eyes. An example of a blue star is the familiar Rigel, the brightest star in the constellation Orion and the 6th brightest star in the sky. Astronomers calculate that Rigel is approximately 700 and 900 light-years away, and yet it appears almost as bright as a star like Sirius which is only 8.3 light-years away.

Betelgeuse Distinctly reddish, it is a semiregular variable star whose apparent magnitude varies between 0.2 and 1.2, the widest range of any first-magnitude star. Betelgeuse is one of three stars that make up the Winter Triangle, and it marks the center of the Winter Hexagon.The star's name is derived from the Arabic إبط الجوزاء Ibt al-Jauzā' , meaning the ha nd of Orion s an early M-type supergiant, Betelgeuse is one of the largest, most luminous and yet one of the most ethereal stars known. A radius of 5.5 AU is roughly 7003118000000000000♠1180 times the radius of the Sun—able to contain over 2 quadrillion Earths (2.15 × 10 15) or more than 1.6 billion (1.65 × 10 9) Suns.

- Gienah Corvi is the right-hand star at the top of the box and one of the pointers to Spica (the other Algorab), as if Spica really needs such. Though the brightest star in the constellation, just over the second magnitude line to third (2.59), Bayer oddly gave it the Gamma designation, Alpha a fourth magnitude star beneath the right-hand side of the prominent box.

Betelgeuse: The Eventual Supernova Credit: ESA/Herschel/PACS/L. Betelgeuse is a star nearing the end of its life. Because it is creating heavier and heavier elements in its core that could be used for stars after it dies, a NASA story once dubbed the red giant a workaholic.

Betelgeuse And for a star, the only thing that defines the temperature of a star is its mass. Blue stars are stars that have at least 3 times the mass of the Sun and up. Whether a star has 10 times the mass of the Sun or 150 solar masses, it’s going to appear blue to our eyes. An example of a blue star is the familiar Rigel, the brightest star in the constellation Orion and the 6th brightest star in the sky.

- Quick Answer. Betelgeuse is 4,000 degrees Fahrenheit cooler than the sun, measuring an effective temperature of 6,000 degrees Fahrenheit compared to the sun's 10,000 degrees Fahrenheit. Despite its lower temperature, Betelgeuse's diameter of 600 million miles is around 700 times the diameter of the sun.

- The coolest stars appear red. That's how the spectrum of a star is related … to its surface temperature. The reason is that the hotter the star, the shorter the wavelength at which the light is most intense in its spectrum. Blue light is of shorter wavelength than red.s a star burns more and more of its fuel, it becomes cooler and cooler, turning the outside yellowish to whitish. When most of its fuel burns out, a star will turn red on the outside.

- Betelgeuse Facts. 1  Betelgeuse is 640 light years from Earth. 2  It is classed as a red supergiant and is the tenth brightest star in the night sky. 3  As part of the Orion constellation Betelgeuse can be easily found in the night sky through most of the year. High mass stars such as Betelgeuse burn their fuel extremely quickly, as a result they exist for only a few million years, stars such as our sun exist for billions of years.
