Betelgeuse

It's around 20 times heavier than our Sun.

As of 2021, Betelgeuse, a red supergiant star in the constellation of Orion, can be seen in the winter night sky in the Northern Hemisphere. It was most recently visible in the night sky in the late months of 2020.

Betelgeuse is not the farthest star from Earth. It is a red supergiant star located in the constellation of Orion, approximately 642.5 light years away from us. There are other stars much farther away from Earth in our galaxy.

Betelgeuse is around 10 times greater in diameter than Rigel.

No. Some time in the next million years Betelgeuse will explode as a supernova, but it is too far away from us to damage the earth. All we will see is Betelgeuse getting a lot brighter in the night sky.

In the movie "Beetlejuice," saying his name three times summons him to the location where he was called. Therefore, if you say Betelgeuse three times in a dark hallway, this action could potentially summon him to that location, leading to unpredictable consequences.

Betelgeuse, a red supergiant star, is so large that if it were placed at the center of our solar system, its surface would extend beyond the orbit of Jupiter. However, as a gaseous object, Betelgeuse does not have a distinct volume like a solid object would.

Betelgeuse is a red supergiant star, and as such, it does not have a defined circumference like a solid object. Its size is measured in terms of solar radii, with Betelgeuse being approximately 1,000 times larger than the Sun.

Yes, Betelgeuse is a red supergiant star located in the constellation of Orion. It is one of the largest and brightest stars in the sky.

Betelgeuse is the eighth brightest star in the night sky and the second brightest star in the constellation of Orin. It is classified as a Red Giant. Astronomers believe that Betelgeuse is only 10 million years old, but has evolved rapidly due to its high mass. Betelgeuse is made from: Helium, Carbon, and Oxygen. Astronomers don't know when but they are sure that Betelgeuse will explode and become a SuperNova. Betelgeuse is 700 million miles in diameter and the surface temperature is 6,000 degrees Fahrenheit. Its luminosity is about 10,000 times the Sun and it's the first star to be directly imaged by a telescope. Finally Betelgeuse is visible in winter skies from the Northern Hemisphere in the constellation Orion.

Hope that Helped You :)

Quite simply because Rigel is still on the main sequence whereas Betelgeuse has come off the main sequence and is only fusing helium in it's core, whereas Rigel is still fusing hydrogen in it's core.

This is the reason for the difference in temperature.

I've heard it pronounced two ways:

1. Beetle-jooz (as in the movie character)

2. BATL-geez (with a long flat a, as in "wade")

It is pronounced ba tle guese

No, Betelgeuse is not a constellation. It is actually a red supergiant star located in the constellation of Orion. A constellation is a group or pattern of stars in the sky, while Betelgeuse is a single star within the Orion constellation.

The red color of Betelgeuse is due to its relatively low surface temperature compared to other stars, causing it to emit more red and orange light. This cooler temperature indicates that Betelgeuse is nearing the end of its life cycle and will eventually explode as a supernova.

No, Betelgeuse is not a quasar. Betelgeuse is a red supergiant star located in the constellation of Orion, while a quasar is a highly energetic and distant active galactic nucleus powered by a supermassive black hole at the center of a galaxy.

No, Betelgeuse is not a main sequence star. It is a red supergiant star, which is a more evolved stage in the life cycle of a star compared to main sequence stars like the Sun. Betelgeuse is near the end of its life and is expected to go supernova in the relatively near future (on astronomical timescales).

Betelgeuse is probably older, but it's hard to give exact ages for stars. Both of them are only a few million years old, much younger than our 4 billion year old sun.

See related questions for more details on the ages of those stars.

Yes, Betelgeuse is a supergiant star. It is a red supergiant star located in the constellation of Orion and is one of the largest stars known in our galaxy.

Traveling to Betelgeuse, which is approximately 642.5 light-years away from Earth, would take a significant amount of time, likely hundreds of thousands of years with current spacecraft technology. The distance is so vast that we don't have the capability to travel there at speeds that would make the voyage feasible in a human timescale.

Yes, it is. Despite being 640 or so light years away from us, it is still one of the brightest stars in our sky, because of its huge size and luminosity.

Rigel appears as bright as Betelgeuse because it is closer to Earth than Betelgeuse, even though Rigel is smaller and less luminous. The brightness of a star is determined by both its luminosity and distance from Earth, so a smaller, closer star can appear just as bright as a larger, more distant one.

Betelgeuse is a red supergiant star located in the constellation of Orion. It is predominantly composed of hydrogen, with smaller amounts of helium and other elements like carbon, nitrogen, oxygen, and trace amounts of heavier elements formed through nuclear fusion processes in its core.

Beleguise is a star located 520 light years away from Earth. This means that the light we see from Beleguise today actually started its journey 520 years ago, traveling through space before reaching our eyes.

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.
