How long will it be until the sun explodes?
Scientists have conducted a lot of researches and study to estimate that the Sun is not going to explode for another 5 to 7 billion years. When the Sun does cease to exist, it will first expand in size and use up all the hydrogen present at its core, and then eventually shrink down and become a dying star.
How close does the sun have to be for us to die?
The sun is about 93 million miles away from Earth, and if we think of that distance as a football field, a person starting at one end zone could get about 95 yards before burning up. That said, an astronaut so close to the sun is way, way out of position.
How much brighter will the Sun get in the future?
And it doesn’t end there. A 10\% increase in brightness every billion years means that 3.5 billion years from today, the sun will shine almost 40\% brighter, which will boil Earth’s oceans, melt its ice caps, and strip all of the moisture from its atmosphere.
What will the Sun look like a billion years from now?
Approximately 1.1 billion years from now, the Sun will be 10\% brighter than it is today. This increase in luminosity will also mean an increase in heat energy, one which the Earth’s atmosphere will absorb.
What will happen to Earth if the sun gets bigger?
It is calculated that the expanding Sun will grow large enough to encompass the orbit’s of Mercury, Venus, and maybe even Earth. Even if the Earth were to survive being consumed, its new proximity to the the intense heat of this red sun would scorch our planet and make it completely impossible for life to survive.
What will happen to life on Earth when the Sun dies?
Life on the planet will run into trouble well before the planet itself disintegrates. Even before the sun finishes burning hydrogen, it will have changed from its present state. The sun has been increasing its brightness by about 10\% every billion years it spends burning hydrogen.
