Can we stop the sun from expanding?
We could counterbalance an asteroid 100 kilometers (62 miles) wide and 10^19 kilograms (2.2 × 10^19 lbs) in weight around the Earth and Jupiter to slowly edge the Earth out of the Sun’s expansion radius over the next billion years.
Will Earth be destroyed when the sun becomes a red giant?
Long before our Sun enters it’s Red Giant phase, its habitable zone (as we know it) will be gone. Astronomers estimate that this zone will expand past the Earth’s orbit in about a billion years. The heating Sun will evaporate the Earth’s oceans away, and then solar radiation will blast away the hydrogen from the water.
What would happen if the sun became a red giant?
In approximately 5 billion years, the sun will begin the helium-burning process, turning into a red giant star. When it expands, its outer layers will consume Mercury and Venus, and reach Earth. Either way, life as we know it on Earth will cease to exist.
What happens when the sun expands?
A: Roughly 5 billion years from now, the Sun will exhaust the hydrogen fuel in its core and start burning helium, forcing its transition into a red giant star. During this shift, its atmosphere will expand out to somewhere around 1 astronomical unit — the current average Earth-Sun distance.
What will happen to Earth when the sun becomes a red giant?
The expanding Sun will engulf the Earth just before it reaches the tip of the red giant phase, and the Sun would still have another 0.25 AU and 500,000 years to grow.

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.
Could the Earth expand to an orbit 50\% more distant?
Even though the Earth could expand to an orbit 50\% more distant than where it is today (1.5 AUs), it won’t get the chance. The expanding Sun will engulf the Earth just before it reaches the tip of the red giant phase, and the Sun would still have another 0.25 AU and 500,000 years to grow.
Is the aging of our Sun a threat to life on Earth?
While the other threats seem a bit exaggerated and current, the aging of our sun into a red giant in 7.6 billion years is a legitimate threat the existence of life on Earth — as well as the Earth itself.
