**Aphelion: The Farthest Distance from the Sun**

**Explanation:**

The distance between the Earth and the Sun varies throughout the year due to the elliptical shape of Earth's orbit around the Sun. This variation causes two important events: aphelion and perihelion.

**Aphelion** occurs when the Earth is farthest from the Sun in its orbit, while **perihelion** occurs when the Earth is closest to the Sun. The Earth reaches aphelion and perihelion at different times of the year due to its elliptical orbit.

Here's why the distance between the Earth and the Sun is greatest during aphelion:

1. **Elliptical Orbit:** The Earth's orbit around the Sun is not a perfect circle but rather an ellipse. This means that the distance between the Earth and the Sun is constantly changing throughout the year.

2. **Aphelion:** Aphelion is the point in Earth's orbit where it is farthest from the Sun. During aphelion, the Earth is about 152 million kilometers (94.5 million miles) away from the Sun.

3. **Perihelion:** Perihelion, on the other hand, is the point in Earth's orbit where it is closest to the Sun. During perihelion, the Earth is about 147 million kilometers (91.4 million miles) away from the Sun.

4. **Timing:** Aphelion and perihelion occur at different times of the year. Aphelion typically takes place in early July, while perihelion occurs in early January.

5. **Seasonal Variation:** The distance between the Earth and the Sun affects the amount of solar radiation received by the Earth. However, the distance is not the primary factor responsible for the seasons. The tilt of the Earth's axis is the main reason for the seasons.

6. **Impact on Climate:** Although the distance between the Earth and the Sun is greatest during aphelion, it does not significantly impact the climate. Other factors such as the tilt of the Earth's axis and the distribution of land and water play a more significant role in determining climate patterns.

In conclusion, the distance between the Earth and the Sun is greatest during aphelion, which occurs in early July. However, this distance does not have a significant impact on climate patterns.
