**Step-by-Step Solution:** 1. **Understanding the Comet's Orbit**: A comet travels in an elliptical orbit around the sun. This means that its distance from the sun changes as it moves along its path. 2. **Identifying Key Factors**: The key factor affecting the length of a comet's tail is its proximity to the sun. The sun emits heat and light, which influence the behavior of the comet. 3. **Effect of Heat on the Comet**: When a comet approaches the sun, the intense heat causes the ice and gases within the comet to vaporize. This process is known as sublimation. ...
