| Effect | Impact on Earth-Sun distance | |--------|-------------------------------| | (via fusion & solar wind) | Weakens Sun’s gravity → Earth spirals outward ~1.5 cm/year | | Tidal interactions (Sun’s gravity on Earth) | Very small effect, also pushes Earth outward | | Gravitational perturbations (other planets, especially Jupiter) | Cyclic variations of ~±3–5% over 100k-year cycles, but no net inward drift |
To address this topic, we need to understand how Earth's orbit works. Our planet follows an elliptical path around the Sun, which means its distance from the Sun varies throughout the year. The closest point in this orbit is called perihelion, and the farthest point is known as aphelion. is earth moving closer to the sun
To put this into perspective, consider the following: | Effect | Impact on Earth-Sun distance |
Although this change is imperceptible on a human timescale, it is driven by fundamental laws of physics that will eventually reshape the solar system. 1. The Annual Seesaw: Perihelion and Aphelion To put this into perspective, consider the following:
