When will the sun destroy the earth

Jun, - by CMI. Astronomers witness star eat its own planet. Earth may share same fate.

There are plenty of ways Earth could go. It could smash into another planet, be swallowed by a black hole, or get pummelled to death by asteroids. There's really no way to tell which doomsday scenario will be the cause of our planet's demise. But one thing is for sure - even if Earth spends the rest of its aeons escaping alien attacks, dodging space rocks, and avoiding a nuclear apocalypse, there will come a day when our own sun will eventually destroy us. This process won't be pretty, as Business Insider's video team recently illustrated when they took a look at what will happen to Earth when the sun finally does die out in a blaze of glory. And as Jillian Scudder, an astrophysicist at the University of Sussex, explained to Business Insider in an email, the day might come sooner than we think. The sun survives by burning hydrogen atoms into helium atoms in its core.

Scientists have been looking into what the future holds for the sun and Earth, and it doesn't look very optimistic. The sun is located a whopping million km away, but can still wreak havoc here on Earth - global warming being an example. But it might not be climate change that's our ultimate demise, but the sun engulfing our planet. A new paper appearing in The Astrophysical Journal looks into Rho Coronae Borealis - a yellow dwarf star that's not dissimilar to our own sun. The star is around the same mass, radius, and luminosity as the sun, with the main difference between the two being their ages. Rho Coronae Borealis is thought to be around 10 billion years old, while the sun is half of that. Researchers found that the star is nearing the end of its lifecycle, meaning it will eventually turn into a red giant. According to scientists, there are four known orbiting planets around Rho Coronae Borealis and they will be impacted by the stellar atmosphere of the transition. Stephen R.

The biological and geological future of Earth can be extrapolated based on the estimated effects of several long-term influences. These include the chemistry at Earth 's surface, the cooling rate of the planet's interior , the gravitational interactions with other objects in the Solar System , and a steady increase in the Sun's luminosity. An uncertain factor is the pervasive influence of technology introduced by humans, such as climate engineering , [2] which could cause significant changes to the planet. Over time intervals of hundreds of millions of years, random celestial events pose a global risk to the biosphere , which can result in mass extinctions. These include impacts by comets or asteroids and the possibility of a near-Earth supernova —a massive stellar explosion within a light-year parsec radius of the Sun. Other large-scale geological events are more predictable.

Researchers debate whether Earth will be swallowed by the sun as it expands into a red giant billions of years from now. By David Appell. The future looks bright—maybe too bright. The sun is slowly expanding and brightening, and over the next few billion years it will eventually desiccate Earth, leaving it hot, brown and uninhabitable. About 7. In its final stage, the sun will collapse into a white dwarf. In some scenarios, our planet escapes vaporization; in the latest analyses, however, it does not. As a result, Earth should drift outward as the gravitational tug lessens over time. At its maximum radius of 1.

Today, the sun is an essential source of gravity and energy. But one day, it will cause Earth's demise. As the solar system 's central star ages, its life cycle will eventually consume our blue marble. So how long does Earth have until the planet is swallowed by the sun?

Once the Sun changes from burning hydrogen within its core to burning hydrogen in a shell around its core, the core will start to contract, and the outer envelope will expand. A lower atmospheric pressure would reduce the greenhouse effect , thereby lowering the surface temperature. Antarctica will reverse direction and return to the South Pole, building up a new ice cap. In the extroversion model, the older, exterior, Pacific Ocean remains preferentially subducted and North and South America migrate toward eastern Asia. Studies of organic sediments have shown that at least kilopascals 0.

All life on Earth owes its existence to the sun's radiant heat.

A high obliquity would probably result in dramatic changes in the climate and may destroy the planet's habitability. This is expected to occur between 1. These periods are caused by the variations in eccentricity , axial tilt , and precession of Earth's orbit. Tectonics -based events will continue to occur well into the future and the surface will be steadily reshaped by tectonic uplift , extrusions , and erosion. On the other hand, a global warming period of finite duration based on the assumption that fossil fuel use will cease by the year will probably only impact the glacial period for about 5, years.

De said, "We are witnessing the future of Earth. The most rapid part of the Sun's expansion into a red giant will occur during the final stages, when the Sun will be about 12 billion years old. There are multiple scenarios for known risks that can have a global impact on the planet. Explosions inside this distance can contaminate the planet with radioisotopes and possibly impact the biosphere.
