the Betelgeuse is colder than the sun
Yes, the Sun is much smaller than Betelgeuse.
Betelgeuse is much bigger than the Sun.
No. The sun is actually hotter than Betelgeuse, but much smaller.
No. While Betelgeuse is larger and brighter than the sun, it actually has a lower surface temperature.
Yeah, the Suns radiant pressure is more increased then Betelgeuse.
Yes, the Sun is much smaller than Betelgeuse.
Betelgeuse is much bigger than the Sun.
It's luminosity is 90,000 - 150,000 times that of the Sun, so it's safe to assume that the total amount of infrared radiation will also be more. Since its temperature is lower than that of the Sun, the percentage of infrared radiation should also be higher.
They do not necessarily have greater luminosity, it depends on their size. Betelgeuse is cooler and brighter; a red dwarf is cooler and less bright.
No. The sun is actually hotter than Betelgeuse, but much smaller.
No. Betelgeuse has 950-1200 times the diameter of the Sun.
No. While Betelgeuse is larger and brighter than the sun, it actually has a lower surface temperature.
Yeah, the Suns radiant pressure is more increased then Betelgeuse.
Betelgeuse is approximately 900 times larger in diameter than the sun, about 1.5 billion kilometers.
Betelgeuse appears smaller than the sun because it is much farther away, by a factor of about 40 million.
No, Betelgeuse has a lower absolute magnitude compared to the Sun. Betelgeuse is a red supergiant star with a much larger luminosity, making it appear brighter despite its greater distance from Earth.
Yes, it has a radius about 1000 times the radius of the sun.
