What would happen if Rigel replaced our Sun?

If Rigel would replace our Sun, all life on Earth would be exterminated since Rigel is at least 2 times hotter than our Sun.

What if Betelgeuse was our Sun?

If you were to replace our Sun with Betelgeuse, it would engulf Mercury, Venus, Earth, Mars, the asteroid belt, and even Jupiter! Over time, as the inevitable supernova approaches, Betelgeuse will shed more mass, continue to expand, dim-and-brighten chaotically, and will burn progressively heavier elements in its core.

Will Rigel become a red supergiant?

Rigel will eventually turn into a red supergiant star. Located at 860 light-years / 260 parsecs away from Earth, Rigel is still so bright that it is considered the seventh brightest star in the night sky.

How far is Rigel from Earth?

864.3 light years
Rigel/Distance to Earth

How close would a supernova have to be?

50 light-years away
Astronomers estimate that, on average, about one or two supernovae explode each century in our galaxy. But for Earth’s ozone layer to experience damage from a supernova, the blast must occur less than 50 light-years away. All of the nearby stars capable of going supernova are much farther than this.

How long will Rigel last?

With an estimated age of seven to nine million years, Rigel has exhausted its core hydrogen fuel, expanded, and cooled to become a supergiant. It is expected to end its life as a type II supernova, leaving a neutron star or a black hole as a final remnant, depending on the initial mass of the star.

Can you see Rigel from Earth?

Rigel is close to zero magnitude in Earth’s sky, making it a bright star, and is best visible in the winter northern sky.

How many light years away is Rigel from Earth?

Rigel is around 800 light years from Earth and is the brightest star in the constellation of Orion. Rigel is actually a three star system consisting of the blue supergiant Rigel A and two distant and much dimmer companions. Age: Approx 8 million years old . Rotation Period: Unknown.

What if Rigel was in the center of the Solar System?

Light from Rigel (left of center) is reflected of the ghostly Witch Head nebula. Rigel has around 75 times the radius of the sun, if it was placed in the center of our solar system it would almost reach the orbit of the planet Mercury. Rigel is estimated to have a maximum mass of around 18 times that of the sun.

What is the maximum mass of the star Rigel?

Rigel is estimated to have a maximum mass of around 18 times that of 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.

What is the temperature of Rigel?

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