How much closer does the sun get to earth every year?

I'm doing a speech about how the world could end, and I know that the sun gets closer every year, but I don't know how much, I think it's like 1.4 or something.

The sun doesnt move closer. I believe it is slowly expanding, it will take likely billions of years before it engulfs the earth and its no more. We will be long gone by then. Also the moon moves 4 inches away each year. It could cause us to spin off our normal orbit. Check that theory out!

No problem! Hope you get some good info and get an A+ :P

The Earth's orbit is eliptical ... so it is closer to the sun during summer, and farther during winter ... by a distance of 3.1 million miles (not much, by solar system standards).

Also ... the moon is moving away from the Earth at 1.5 inches (or 3.8 cm) each year.

Earths orbit does not contribute to seasons, its the tilt of the axis.

It's both, actually ... the Earth IS closer to the sun during summer, which contributes to the increase temperatures.

We are farther from the sun in July , and closer in January , we are considered to be in a circular orbit, it's not a perfect circle, still, it's our tilt that allows for the seasons, not distance from sun.

Right I understand its not a perfect circle, but the tilt of the axis is why we have different seasons.

Yes.

I read the orbit is expanding, not contracting. Also, in( about) 5 billion years, the Sun (they say) will expand and engulf the inner planets...
