What if the date of perihelion (when Earth is closest to the Sun) changed from January 3 to June 10, and all of the other orbital parameters (tilt and precession) remained the same as they are today. What would this effect the intensity of the season in each hemisphere?

The Answer is If the date of perihelion changed from January 3 to June 10, it would mean that Earth would be closest to the Sun during the month of June instead of January. This change would have a significant impact on the intensity of the seasons in each hemisphere.

In the Northern Hemisphere, the change in perihelion date would result in the Earth being closest to the Sun during the summer months. This would lead to a more intense summer season, with higher temperatures and potentially more extreme weather patterns. Conversely, the winter season in the Northern Hemisphere would be less intense, with milder temperatures and potentially less snowfall.

In the Southern Hemisphere, the opposite effect would occur. The change in perihelion date would result in the Earth being closest to the Sun during the winter months. This would lead to a more intense winter season, with lower temperatures and potentially more snowfall. The summer season in the Southern Hemisphere would be less intense, with milder temperatures and potentially less extreme weather patterns.

Overall, the change in perihelion date would lead to a shift in the intensity of the seasons in each hemisphere, with potentially significant impacts on weather patterns, temperature extremes, and overall climate conditions.
