We all know that the Sun is the ultimate source of energy for all lives on earth. The sun is a star consisting of basically hydrogen and helium. It is about 109 times that of the earth in size and about 330,000 times the mass. Yes, it is that huge. Most of us take the sun for granted but it is the divine virtue of the sun that it still keeps on shining and provide us with heat, light, and energy. But have you ever wondered, what happens to the earth and us if the sun suddenly runs out of gas and turns off ⚫?? Have you thought of the events that might occur apart from the chaos when the sun is gone? If not, don’t worry the curiousguru is on the rescue ⛑️
Will we see light if the sun dies?
It is obvious there will be no light without the sun but the time for light to reach the earth is 499 seconds (At average distance), so the last beam of light leaving from the horizon of the sun before it dies will take about eight and a half minutes to reach the earth’s horizon and there will still be natural light for a couple of minutes. This will be the last time that we ever experience sunlight and after that, the entire earth will be plunged into darkness and we will only rely on the artificial light produced from electricity, firewood, or chemical energy ( candles, kerosene lamps, etc.) until they exhaust as well.
Will the moon be visible if the sun dies?
The moon does not produce light of its own, it reflects the light that it receives from the sun. So in the absence of the sun, though it might be present the moon will not be visible. No sun; no moon. Since stars produce their heat and light, they will be the only entity you could see when you look up in the sky, regardless of the time in your clock, because there will be no light to outshine them.
What will the temperature of Earth be if the sun dies
For the first 24 hrs, the temperature will not drop drastically due to the greenhouse effect which traps heat to keep the earth’s surface warm in absence of the sun, and in addition, the core of the earth provides heat from the inside.
But from the very next day the temperature on the surface of the earth will drop 15 – 20o C and in a week or so it will go below 0o C . Soon after a year, the earth will revert to ice age but with a much lower temperature ( below -100oC) than before due to the absence of sunlight and probably with no life this time.
How much time will we survive if the sun dies
We all know that plants need sunlight to perform photosynthesis, which is their process of manufacturing food but with the sun being gone there is no way they can produce energy for their survival, so evidently, all small plants and trees will start dying off. Due to slow metabolism, bigger trees will survive for a while but death is imminent in a few weeks. The end of plant life will result in the extinction of herbivores and many other animals that depend on plants for food and ultimately the whole food chain will fall. Humans will survive only until their food reserves last because we will run out of food long before we run out of breathable air.
If humans were to survive only on oxygen after all plants died then we would have about 10 million days which is about 27,397.26 years before we run out of oxygen.
Assuming the planet is not destroyed, some psychrophilic bacteria will be the last to die because they can survive extreme cold climate but as soon as the temperature drops below their incubation conditions they will not be able to survive either.
What happens to the solar system if the sun dies
The earth revolves around the sun in an imaginary path called the orbit. An orbit is a gravitationally curved trajectory of an object that all planets and satellites follow. The gravitational force of the sun holds all the planets in an organized manner in the solar system in their orbits but with the death of the sun, the gravitational force vanishes along with it. As a result, now the planets do not have a definite path of travel and no force to direct their movements so they will scatter around the galaxy. In this case, our precious earth might collide with an asteroid, a moon, or any other planet which will destroy the planet in the blink of an eye.
Well, these were just assumptions and we don’t have to worry about the death of the sun anytime soon because the sun has been burning since 4.5 billion years and still has more than 5 billion years before it exhausts its resources. And even after that, the sun does not die but on the contrary, it will turn into a red giant and start engulfing the nearby planets like mercury, venus, and earth probably. So either way, we won’t be alive to witness these events.
Do you think we would be able to survive for a week without the sun? Reply in the comments.
