How does the size of Rigel compare to the size of our sun?

How does the size of Rigel compare to the size of our sun?

Its surface temperature is also far hotter than the sun, around 21,000 degrees Fahrenheit (11,600 degrees Celsius). Compare that to 10,000 degrees F (5,500 degrees C) for the sun. In terms of overall size, Rigel measures 79 times the diameter of the sun. And yet, it’s only 21 times more massive.

How does our sun differ in size and temperature from the star Rigel?

Rigel’s diameter is about 40 million miles, meaning that if it were put in the sun’s place, it would only swallow Mercury. However, Rigel has about 50 times the mass of our own sun and is just about twice as hot at 12,000 degrees Kelvin.

What is the size of Rigel?

34.11 million mi (78.9 R☉)
Rigel/Radius

How does the size of the Sun compared with the size of a giant star and a supergiant star?

It puts out about 60,000 times as much energy, and is 60 times bigger than our star. And there are stars that are far more impressive. Blue supergiants can reach sizes 1,000 times larger than the Sun. It has a radius about 1,650 times that of the Sun.

Is Rigel a high mass star?

Distance, Size, and Mass Rigel is estimated to have around 21 solar masses. However, Rigel is losing around 10 million times more mass than the rate of the Sun.

Is Rigel or Betelgeuse bigger?

Betelgeuse is a red supergiant — the largest class of stars. Rigel is a blue supergiant. Like Betelgeuse, it is much bigger and heavier than the Sun. It’s surface is thousands of degrees hotter, however, so it shines blue-white.

Is Barnard’s star hotter than the Sun?

Even so, the lower mass of Barnard’s Star makes it about 2,500 times less powerful than our sun. In other words, Barnard’s Star is much dimmer and cooler than our sun.

Which star is bigger Rigel or Betelgeuse?

What is the lifespan of the Rigel star?

Blue supergiants like Rigel usually exhaust their fuel at a far quicker rate than smaller stars. Because of this, these types of stars tend to live only a few million years. Rigel has been estimated to be just 8 million years old and has already depleted its supply of hydrogen at its core.

Is Rigel temperature higher than the Sun?

Rigel is estimated to have surface temperatures of around 12,000C (22,000F), more than twice as hot as the sun . Rigel is a blue supergiant star with a luminosity more than 100,000 times that of the sun.

Is Arcturus bigger than the Sun?

Arcturus has been calculated as 25.40 times bigger than the Sun. The Sun’s radius is 695,800km, therefore the star’s radius is an estimated 17,673,320.00.km. If you need the diameter of the star, you just need to multiple the radius by 2.

Is the North Star bigger than the Sun?

Scientists using a new telescope found the size of the North Star, also known as Polaris . It turns out that Polaris is 46 times larger than the Sun.

How much are bigger than Antares is the Sun?

While Antares’ diameter is about 700 times larger than the sun in visible light, this map revealed that, as seen in radio light, the star’s atmosphere stretches even farther and is even more enormous.
