What happens if the earth is closer to the sun?

Answer 1

The Earth becomes hotter

To be more precise, our atmosphere would ignite, we would be exposed to super-heated solar winds and roast.

Edit:

Earth gets closer to the sun every year. That's why we have summer. It depends on how much closer it gets.

Answer 2

Depends on how much closer.

The earth's orbit varies from between 152,098,232 kilometres (94,509,460 mi) to 147,098,290 kilometres (91,402,640 mi), so a difference of a few million kilometers doesn't make that much difference.

The temperature difference in the seasons happen because of the angle the sun hits the earth (that's why it is summer in the Southern Hemisphere when it is winter in the northern hemisphere).

Answer 3

If the Earth were closer to the Sun, temperatures would rise significantly, leading to extreme heat and potentially making the planet uninhabitable. The closer proximity could also disrupt the delicate balance of ecosystems and weather patterns on Earth.
