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 would happen if the Sun and Earth switched places?

The Solar System is finely balanced, with the gravitational pull of each body almost perfectly keeping all the planets in a stable orbit. On the flip side, Earth would receive half as much sunlight, and thus the planet would freeze over.

Is Rigel bigger than the Sun yes or no?

An example of a larger star than our Sun is the blue supergiant Rigel in the constellation Orion. This is a star with 17 times the mass of the Sun, which puts out 66,000 times as much energy. Rigel is estimated to be 62 times as big as the 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.

Why is Rigel important to astronomers?

Rigel is a blue supergiant that is the brightest star in the constellation Orion (the Hunter). Due to its measured size and brightness it is expected to end in a supernova one day. Rigel is more properly (to astronomers) known as Beta Orionis. …

What are two interesting facts about Rigel?

Rigel Star Notes – Though we see it as a single star, Rigel is actually a quadruple star system. – Rigel is the brightest star in the constellation of Orion and the seventh brightest star in the night sky. – Rigel is designated as Beta Orionis. – Rigel is more than 100 times bigger than our Sun and twice as hot.

Why is Rigel brighter than the sun?

Rigel, which comes from a corruption of the Arabic word for “the left leg of the giant” is a supergiant star. It’s temperature (36,000 F) is much hotter than the Sun’s (10,000 F) and its brightness is about 47,000 times that of the Sun….Rigel.

How does Rigel compare to the 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.

Will Rigel become a black hole?

Rigel’s large mass (18 times that of the sun) will mean Rigel will become a black hole. When the star runs out of fuel, it can no longer push gravity back, and the core will collapse. After the core collapses on itself, gravity, pushing against the star, will compact the core until it is very small.

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.

Why is Rigel brighter than the Sun?

Even though much of Rigel’s energy is emitted as invisible ultraviolet light it is still around 40,000 times brighter than the sun. High mass stars such as Rigel exhaust their fuel at a far quicker rate than smaller stars, as a result they exist for only a few million years.

How hot is the surface temperature of the star Rigel?

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.

What will happen to the star with the name Rigel?

Rigel to astronomers. Astronomers believe the star is about 10 million years old and that later in its life, it will likely transform into a red supergiant (just like Betelgeuse) and eventually explode into a supernova, Kaler added.
