Web18 jun. 2024 · When Mercury is at its closest point to the Sun, the Sun really is about 50% bigger than when Mercury is at its farthest point from the Sun. This elliptical orbit also gives Mercury seasons that are very different. On Earth, seasons are due to the 23-degree tilt of Earth’s axis, where northern winter coincides with southern summer and vice versa. Web8 okt. 2024 · The main reason for the planets to vary their distance is due to elliptical orbits. No planet in our Solar System orbits the sun in a perfect circle which means that the distance between planets is never the same. For this reason, to calculate the distance, we use the average to measure how far planets are from one another.
