Is the earth moving closer to the sun or moving away?

This is an image of the Earth at night seen from space (city lights can be seen). You can only see the Northern hemisphere, with North America on the left, and Europe on the right. In the middle of the far distance you can see the sun as a solar flare, lighting up the other side of the Earth.

The Sun moves in such a predictable way across the sky that you might never suspect that its relationship to Earth is changing all the time. In fact, the average distance between the Earth and the sun is not static over the years. Do we know if The Earth is it moving closer or further away from the sun? And what forces act on our planet and our star to make this happen?

In short, on sun moves away from Earth with time. On average, Earth is about 93 million miles (150 million kilometers) from the sun, according to NASA (opens in new tab). However, its orbit is not perfectly circular; it has a slightly elliptical or oval shape. This means that Earth’s distance from the sun can vary from about 91.4 million to 94.5 million miles (147.1 million to 152.1 million km), NASA (opens in new tab) says.
