Answer 2

When the orbital eccentricity of a planet is close to 1, it means that the planet's orbit is highly elongated and less circular. An orbital eccentricity of 1 would signify a perfectly elliptical orbit, while a value close to 0 indicates a nearly circular orbit.

In practical terms, a planet with high eccentricity experiences significant variations in its distance from the Sun throughout its orbit, resulting in different levels of solar energy received at different points in its orbit. This can lead to extreme differences in temperature and other climate conditions between the closest and farthest points in its orbit.

For example, Pluto, which has an eccentricity of 0.25, experiences significant seasonal variations due to its elliptical orbit. When the planet is closest to the Sun (perihelion), it receives more solar energy, resulting in a relatively warmer period. Conversely, when it is farthest from the Sun (aphelion), it receives less solar energy and goes through a colder period.

Therefore, a planet with an orbital eccentricity close to 1 would have a larger range of temperature extremes and more pronounced seasonal variation compared to a planet with a smaller eccentricity.
