What happens if you replace the sun with Orion alpha star?
Orion alpha is 900 times the size of the Sun, and astronomers believe that the four will explode soon. What happens if our earth revolves around the big beast in this star?
Orion alpha star, Orion alpha star, Orion alpha star, important three times. But unlike the routines in the movie, you need to say it three times in a row to get the Orion alpha star to appear in front of your eyes. You just have to look up and see it.
Orion alpha star has a place among the ten brightest stars. In the clear night sky, you can clearly see the red light of the Orion alpha star.
Although the Orion alpha star is brighter than our sun, can it replace our sun? What if the earth rotates around this red superstar?
We are able to see the Orion alpha star 640 light years so clearly because it is really big. In fact, the Orion alpha star is 12 to 20 times larger than the Sun. Orion alpha stars occupy 900 times the space actually occupied by the sun, and the brightness is 100,000 times that of the sun.
Surprisingly, although the Orion alpha star is very large, its temperature is not high. A small tip: the temperature of the stars determines their color.
If they look red, then their temperatures are generally low, about 3,000 degrees Kelvin. The temperature of the blue stars is the highest, and their temperatures can even reach more than 30,000 degrees Kelvin. The temperature of the yellow star is between the two, about 6000 degrees Kelvin, just like our sun.
So even though the Orion alpha star is brighter than the sun, can we expect it to cool the earth? the answer is negative.
Let us clarify this matter. The Orion alpha star is not only a little bigger than the sun, it is 900 times larger than the sun. The superstar is the largest star in our universe, so it is conceivable what would happen if you place such a huge star in the center of the solar system.
First, let’s say goodbye to Mercury, Venus, Earth, and Mars. Because the Orion alpha star is too big, if you let it replace the sun, it will immediately swallow the planet near the sun. The surface of the Orion alpha star extends beyond Mars and even reaches Saturn.
As a pulsar, the diameter of the Orion alpha star changes periodically, so even a planet outside its diameter is not completely safe.
The Orion alpha star loses some of its mass when it expels a large group of gases, and if it is in the sun’s position, it can be blown to Neptune.
You may also see it, we have not created a fair condition for this hypothesis. To say that if the Orion alpha star replaces the sun, everyone will die immediately and it seems to be an escape. So let’s assume that the Orion alpha star is in a position that is safe enough for us to provide us with enough light and heat, just as the sun is to us.
Well, you will live an ordinary life, and then… die before your first birthday, because the Earth takes more than 300 years to circle around Orion. Um… I wish you a happy birthday, or not.
So the next time you look up at the starry sky and see the Orion alpha star, you should be glad that you can see it at a safe distance. But don’t be happy for too long, because scientists predict that Orion alpha will explode soon.
In fact, the explosion may have happened. When the light of the explosion reaches Earth, it will be the brightest supernova in human history, tomorrow or 100,000 years later. The brightness of the light may even rival the moon. But at least we are not so close to the Orion alpha star, or else we have long since disappeared.
Orion alpha is the ninth brightest star in the night sky and the second brightest star in Orion (second only to the seven). It is a slightly reddish semi-regular variable star with a star magnitude between +0.0 and +1.3, which is the widest of the first class stars. In the near-infrared band, the fourth is the brightest star in the night sky. According to the Valle star nomenclature, the Orion alpha star is called Orionis alpha, Alpha Orionis Latin, abbreviated Alpha Ori or alpha Ori.
