What would happen if the sun were much closer to or further from the Earth?

You might have seen somewhere that if Earth were 10 feet closer to the sun, we would all burn up, 10 ft further and we’d freeze to death. The following week it’s moving away from the Sun by about 100 miles each hour, a month from then it’s more like 600 miles each hour.

What would happen if Earth moved 1 mile closer to the sun?

If the Earth was a mile closer, temperature would increase by 5.37×10−7\% . For the change in temperature to be noticeable, Earth would have to be 0.7175\% closer to the sun.

What if the sun moved twice the distance from Earth?

Doubling the distance from the sun reduces gravitational pull and increases the orbital period.

What would happen if a planet fell out of orbit?

In other words, anything on the Earth’s leading side would fly off into space, continuing along the Earth’s orbital path around the sun. Anything on the trailing side would be pulverized against the Earth. It would be a horrible, gooey mess.

What happens when the distance between Earth and the Sun decreases?

When the distance decrease by a mile the temperature on Earth increases by 5.37 ×10−7 \%. A simpler answer. almost anything. During a year the distance Sun-Earth varies by 5 million km. And this effect has little effect on seasons. Actually, the Sun is closer in Winter and farther in Summer (for Northern hemisphere).

Are We moving towards or away from the Sun?

Well, there are some long-period oscillations, but those are very small, and don’t imply that we’re systematically moving towards or away from the Sun. There is an effect which is making us move very slowly away from the Sun. That is the tidal interaction between the Sun and the Earth.

How much closer to the sun does the Earth have to be?

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.

How do tides affect the Sun-Earth system?

That is the tidal interaction between the Sun and the Earth. This slows down the rotation of the Sun, and pushes the Earth farther away from the Sun. You can read about tides, as they relate to the Earth-Moon system here. The principle for the Sun-Earth system should be the same. But how big of an effect is this?
