Since the earth is at its nearest point to the sun during northern hemisphere’s winter/southern hemisphere’s summer, and?
the earth is at its farest point to the sun during northern hemisphere’s summer/southern hemisphere’s winter
Shouldn’t the summer of Southern Hemisphere be slightly hotter than the summer of northern hemisphere
the winter of Southern Hemisphere be slightly colder than the winter of northern hemisphere
But why is the real situation not like this at all
Why does this kind of situation happen in the Mars
Mars’s northern hemisphere has a mildly warmer summer and a mildly colder winter
On the other hand, Mars’s southern hemisphere has a hotter summer and a colder winter

The real situation is just as you describe but is mitigated by the fact that there's less land in the Southern Hemisphere and the whiteness of Antarctica reflects heat back into space.

Antarctica has not just an Ice Capped Continent.
But a Wide Ocean surround it which disapates the Heat
the North Pole does not have that problem, Surrounded by landSource(s): The two Poles are like Yin and Yang

That variation of solar distance has literally no effect on earth temperatures, not even one degree.
Southern hemisphere is warmer due to less land and more water, the north, more land and less water.

In Ears case, yes, Sus tralia DODS have a slightly warmer summer in the outback, but closer to the coats where water, which has a a high heat capacity and warms up and cools down slowly, the casts aren't affected as much. Australia's geomorphology ia also different..There are higher mountain ranges along the was, coast of Australia than the eat cost of North America. . the highest recorded Temperature on Earth is in California, but there are large parts of the Australia outback we don't have data for.
Wile Mars d
Rotational axis is currently tilted at to the perpendicular the plabe of its orbit, Mars has a more eccentric orbit than Earth has. I would have to loom up when what season it is on mars when Mars is at perihelion and aphelion. There is also a difference I. Else ovation of Mars' northern and southern hemispheres, there is no liquid water on Mars surface, and Mars has much thinner atmosphere than earth. Earth doesnt gat carbon dioxide snow freezing and following as snowSource(s): like Mars does. Mars has much bigger north pole ice cap in winter than Mars south pole. Mats north pole is tilted toward the Sun at aphelion, but because mars is moving more slowly at Aphelion, the season is 24 days longer than at Mars south pole is tilted away from the Sin at perihelion. https://science.nasa.gov/science-news/science-at-n...

Disclaimer: I'm not an astronomer.
The largest radius from Earth to the Sun in the year (aphelion) is 1.0167 astronomical units, and the smallest radius (perihelion) is 0.98329 (https://en.wikipedia.org/wiki/Earth%27s_orbit). These number are pretty close (1 astronomical unit is approximately the average distance between the Earth and Sun, or 1.495978707×1011 m). So the orbit is almost a circle. So the distance from the Sun does not even change that much. What's more important is which part of the Earth directly faces the Sun, and which part faces away, since this can affect how much heat is collected.
Also, the axis on which the Earth spins can wobble, and the orbit can change slightly depending on the Moon and planets and stuff. So the date of the year when the Earth is closest/furthest from the Sun might change over time (https://en.wikipedia.org/wiki/Axial_tilt#Earth). So it might be a different day in different years.
Many other factors affect the temperature distribution, such as land distribution. The northern hemisphere holds most of the land, while the southern hemisphere holds most of the water. However, the north pole is mainly water surrounded by land, while the south pole is mainly land surrounded by water. The oceans circulate a lot of heat around the world, and thus prevent temperature extremes (ie very hot or very cold weather), "smoothing out" the temperature to closer to average. This is why inland areas typically have more extreme weather (ie very hot or very cold) while coastal areas have a more regular consistent temperature. It is also why the south pole gets a lot colder than the north pole. Ocean currents can bring warmth into the north pole during winter. But they cannot bring warmth to the south pole during winter, because it is mostly land.
"The Arctic's ice is relatively thin compared with Antarctica and it has water, not land, under it. While the water is not warm, it usually stays around 30° F, which is often significantly warmer than the air above the ice. Some of this heat makes its way through the ice to the air moderating temperatures somewhat." (https://divediscover.whoi.edu/polar-regions/compar...
Also, different types of land, ice, vegetation, and water collect heat from sunlight very differently, which can also affect how heat is caught even more.Source(s): Blessed enough to go to school

The southern hemisphere summer DOES get slightly more solar energy than the northern hemisphere summer, and its winter gets slightly less. But because so much more of the southern hemisphere is ocean, both extremes are dramatically reduced.
If the continents were arranged so that the land-masses in both hemispheres were roughly equal, the southern hemisphere absolutely would have hotter summers and colder winters.
Because Mars has no oceans, their mitigating influence doesn't exist, and southern hemisphere summers and winters are both more extreme than in the northern hemisphere. And as Mars' orbital eccentricity is 5.5 times greater than Earth's, the extremes are even more pronounced.
