Betelgeuse

Betelgeuse is located in the Orion constellation and is a red star. Red stars are generally the coolest of stars.

The star you're looking for to tell direction is Polaris, the North Star.

If you know what time it is, and have an accurate star map, you could use Betelgeuse to tell direction, but it's difficult.

Betelgeuse ("Beetlejuice") has a surface temperature of around 3,500 Kelvin. (3,200º Celsius or 5,800º Fahrenheit)

Betelgeuse is a semiregular variable star located in the constellation Orion.

It is the second brightest star in the constellation and the ninth brightest star in the night sky.

It has an apparent magnitude of 0.58 (Var 0.3 -> 1.2) and an absolute magnitude of -5.14.

The right ascension of Betelgeuse changes by approximately 2 hours during that time frame. As the Earth rotates, the position of stars in the sky appears to change, resulting in the change in right ascension of Betelgeuse from midnight to 6am.

It is a Red Giant.

No, Rigel is hotter than Betelgeuse. Rigel is a blue supergiant star with a surface temperature of around 12,000 Kelvin, while Betelgeuse is a red supergiant with a surface temperature of around 3,500 Kelvin.

The constellation containing Betelgeuse and Rigel is Orion. It is one of the most recognizable and prominent constellations in the night sky.

Betelgeuse is a red supergiant star located in the constellation of Orion. It is one of the brightest stars in the night sky and can be easily seen with the naked eye in the Orion constellation, particularly in the "shoulder" area of the Orion constellation.

Betelgeuse is hotter than Vega. Betelgeuse is a red supergiant star with a surface temperature of around 3,500 degrees Celsius, while Vega is a blue-white star with a surface temperature of around 9,600 degrees Celsius.

Betelgeuse is estimated to be around 8 to 8.5 million years old.

The red color of Betelgeuse indicates that it is a cooler star, emitting light at longer wavelengths in the red spectrum. This color indicates that Betelgeuse is a massive, aging star that is nearing the end of its life cycle.

Betelgeuse boasts the diameter greater than the orbit of Jupiter. It has a mass of around 20 times the mass of the Sun, and its luminosity is almost 200,000 times greater than the Sun. So really, it is one of the biggest and brightest stars ever observed.

It's estimated to be about 640 light years away. However there's still a lot of uncertainty over the exact distance.

The closest star to Betelgeuse is approximately 643 light-years away. This star is located in the star cluster known as the Orion Nebula, where it is part of a group of young, hot stars.

Betelgeuse is approximately 430 light years away from Earth, while Capella is about 42.9 light years away. Therefore, Betelgeuse is around 387.1 light years farther away from Capella.

Rigel is brighter than Betelgeuse. Rigel is a blue supergiant star that is one of the brightest stars in the night sky, while Betelgeuse is a red supergiant star that is dimmer in comparison.

Yes, it has a radius about 1000 times the radius of the sun.

Betelgeuse is approximately 643 light-years away from Earth, which translates to about 193 parsecs or 1980 trillion kilometers. In astronomical units (AU), where 1 AU is the average distance between the Earth and the Sun, Betelgeuse is located over 900,000 AU away.

A red super giant star nearing the end of its life. It is currently fusing helium in its core. Betelgeuse is expected to explode as a type II supernova, possibly within the next million years.

Rigel appears as bright as Betelgeuse even though it is further away because Rigel is intrinsically brighter (has a higher luminosity) than Betelgeuse. Despite being further away, its higher luminosity compensates for the distance, making it appear similarly bright in the sky.

Betelgeuse is much larger than the Sun. It is a red supergiant star, with a radius around 650-900 times larger than the Sun. If placed in our solar system, Betelgeuse would engulf all the inner planets including Jupiter.

Betelgeuse is about 640 light-years from the sun.

Betelgeuse appears bright in the night sky because it is a massive red supergiant star, about 1000 times larger than our Sun. Despite being much farther away from us than the Sun, its large size and high luminosity make it one of the brightest stars in the sky. Its reddish color also makes it stand out.
