A less dramatic shift in Earth's orbit would primarily affect the planet's temperature. The closer you are to the sun, the hotter the climate. Even a small move closer to the sun could have a huge impact. That's because warming would cause glaciers to melt, raising sea levels and flooding most of the planet. Without land to absorb some of the

Overall, if the sun moved closer to Earth, it would likely make the planet inhospitable for most forms of life, including humans. The increased heat and solar radiation would have far-reaching consequences on ecosystems, weather patterns, and the overall balance of life on Earth. It is crucial to maintain the current distance between the sun

Now, if you adjust Earth's semi-major axis, which makes the orbit faster or slower, and changes the length of the year - with that, there's much less variation. @JThistle covered this. If you push Earth's semi-major axis just a few percentage points closer to the sun, Earth would heat up and it would get bad quickly.

On average, Earth is about 93 million miles (150 million kilometers) from the sun, according to NASA. However, its orbit is not perfectly circular; it's slightly elliptical, or oval-shaped. This

https://nineplanets.org/questions/getting-closer-sun/
We are not getting closer to the sun, but scientists have shown that the distance between the sun and the Earth is changing. The sun shines by burning its own fuel, which causes it to slowly lose power, mass, and gravity. The sun's weaker gravity as it loses mass causes the Earth to slowly move away from it. The movement away from the sun is

Earth has an eccentric orbit, which means that it moves in a path that is slightly oval in shape. Contrary to what you'd expect, Earth gets closest to the sun every December, and farthest from the sun every June. We in the northerhe maximum eccentricity is about 5 percent and the minimum is near zero, when the orbit is nearly circular.

If Earth moved closer to the Sun, it would have significant effects on the planet's orbit and seasons. Firstly, a closer proximity to the Sun would cause the Earth's orbital speed to increase. This is because the gravitational force between the Earth and the Sun is inversely proportional to the square of the distance between them.

https://magnifymind.com/sun-approaches-earth/
The Sun is 149,600,000 km away from Earth, which corresponds to an average distance of about 150 million km or 1 Astronomical Unit (AU). However, actually, the Earth moves in an ellipse around the Sun and we come a little closer to it (about 147 million km) at perihelion (January 3rd) and move away from it (152 million km) during aphelion (July 4th).

It is Earth's relationship to the sun, and the amount of light it receives, that is responsible for the seasons and biodiversity. The amount of sun a region receives depends on the tilt of Earth's axis and not its distance from the sun. The Northern Hemisphere experiences summer during the months of June, July, and August because it is tilted toward the sun and receives the most direct

For Earth, that means a 3 /T 2 is equal to 1. For Mercury, the closest planet to the Sun, its orbital distance, a, is equal to 0.387 astronomical unit, and its period, T, is 88 days, or 0.241 year. For that planet, a 3 /T 2 is equal to 0.058/0.058, or 1, the same as Earth.

If Earth were to move closer to the sun, it would mean far more intense heat on the planet. Glaciers all over the world would melt rapidly, causing a rise in sea levels and global chaos. Basically, the planet would be flooded. If Earth moved farther from the sun, however, all the bodies of water on the planet would freeze, basically freezing

The sun moves in such a predictable way across the sky that you might never suspect that its relationship with Earth is changing all the time. In fact, the average distance between Earth and the sun is not static year over year. So do we know if Earth is getting closer to or farther from the sun? And what forces are acting on our planet and our

If the Earth was a mile closer, temperature would increase by 5.37\times10^{-7} %. For the change in temperature to be noticeable, Earth would have to be 0.7175% closer to the sun. The average surface temperature of the Earth as a result of it bathed by sunlight can be calculated by assuming that both the Earth and the Sun are blackbodies and the Earth is in radiative equilibrium with the Sun

https://science.nasa.gov/solar-system/orbits-and-keplers-laws/
Kepler's three laws describe how planets orbit the Sun. They describe how (1) planets move in elliptical orbits with the Sun as a focus, (2) a planet covers the same area of space in the same amount of time no matter where it is in its orbit, and (3) a planet's orbital period is proportional to the size of its orbit.

The distance between the Earth and the sun varies during the year because of the planet's slightly elliptical orbit. At its closest approach, Earth is about 3 million miles closer to the sun than at its farthest point. As a result, sunlight is about 7 percent more intense when Earth is closest to the sun.

https://www.nasa.gov/missions/station/iss-research/studying-the-sun/
The Sun wields a huge influence on Earth. Its gravity holds our planet in its orbit, and solar energy drives the seasons, ocean currents, weather, climate, radiation belts, and auroras on Earth. The solar wind, a flow of charged particles from the Sun, constantly bombards Earth's magnetosphere, a vast magnetic shield around the planet.

Approximately every 11 years, the sun undergoes a remarkable metamorphosis: its magnetic poles flip. Unlike Earth, which experiences pole reversals on a geological timescale of hundreds of thousands of years, the sun's magnetic shuffle is a regular occurrence that marks the peak of the solar cycle. The last reversal took place in 2013, so the
