the orbit of earth itself is pretty eccentric (not a perfect circle). The distance between our planet and the sun varies by quite a large margin throughout the year, and yet the temperature variance in any given place isn’t all that huge. What actually causes earth to be at the temperature range that it is is that the planet rotates on its own axis, along with having our atmosphere. It heats up while facing the sun (day) and cools down when it’s not (night). This is also why summer and winter seasons are swapped between the hemispheres. That detail dictates whether the day is longer than the night during a time of year and thus if that side of the planet spends more time facing towards or away from the sun on a given day.
