# Earth's Orbit Change: Impact on Life - Will We Die?

• night_stroller
In summary, if the Earth's orbit were forcibly moved 1% off its current position, it would not cause us to die but it would result in a drop in temperature. This is because a stable distance from the Sun is necessary to maintain the temperature that allows for life on Earth. However, since the Earth already varies its distance by 2.6% due to its elliptical orbit, the difference may not be noticeable. But if the Earth were 1% further off, the total energy received from the Sun would also decrease, resulting in a significant temperature drop.

If the Earth was forcibly moved 1% off it's current orbit, What would happen to life? How would it be any different from what it is now? Will we die?

We won't die. Since a stable distance is needed to maintain a certain temperature which allows life possible on Earth (with greenhouse effect in play as well, else wise the average surface temperature would be -18 with its current position), the 1% off its current orbit won't move us far enough where temperature would decrease and making Earth cold.

Considering that the Earth varies its distance from the Sun by some 2.6% already just by virtue of the eccentricity of its orbit, I don't think you'd notice much difference.

The two cases are different. The Earth's orbit is elliptical with the difference is 2.6%, but the heat at periphelion can be preserved to the aphelion time because we have a lot of water.
If the Earth were 1% further off, the total energy the Earth received is also off by square.
I don't think we would die, but the temperature would drop quite considerably.

## 1. How does Earth's orbit change impact life on Earth?

Earth's orbit change can have a significant impact on life on Earth. It can affect the planet's climate, seasons, and even the length of a day. Changes in Earth's orbit can also alter the amount of solar radiation received, which can impact plant growth and animal behavior.

## 2. What causes Earth's orbit to change?

There are several factors that can cause Earth's orbit to change. The main cause is gravitational interactions with other objects in the solar system, such as the Moon and other planets. Changes in the distribution of mass on Earth, such as melting ice sheets, can also affect its orbit.

## 3. How often does Earth's orbit change?

Earth's orbit is constantly changing, but the changes are usually very small and occur over long periods of time. Major changes, such as changes in the tilt of Earth's axis, occur on a cycle of about 41,000 years.

## 4. Will humans die as a result of Earth's orbit change?

No, it is unlikely that humans will die as a direct result of Earth's orbit change. However, these changes can have indirect effects on our planet's climate and environment, which can impact human life in various ways.

## 5. Can we predict and prepare for Earth's orbit change?

Yes, scientists can predict and track changes in Earth's orbit using mathematical models and observations. This allows us to understand and prepare for potential impacts on our planet's climate and environment. However, it is important to note that predicting long-term changes in Earth's orbit is still a complex and ongoing area of research.
