Is Earth getting closer to the sun, or farther away?

The sun moves across the sky in such a predictable way that you might never guess that its relationship with the earth is constantly changing. In fact, the average distance between the Earth and the Sun is not static year after year. So we know if Earth are you getting closer or farther away from the sun? And what forces are at work on our planet and our star to make this possible?

In short, the Sun moves farther and farther away from Earth over time. On average, the 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 is slightly elliptical or oval in shape. This means that Earth’s distance from the Sun can range from about 91.4 million to 94.5 million miles (147.1 million to 152.1 million km). NASA (opens in new tab) says.
