Question

how earth affected if it is too nearer to sun answer in detail ​

Answer 1

Answer:

On January 4, 2003, our Earth made its closest approach to the Sun for the year-- an event astronomers call perihelion. At perihelion, the Earth is about 147.5 million km away from the Sun. (At the greatest separation, the two are about 152.6 million km apart - which will occur this year on July 4.) Relatively speaking, Earth's distance from the Sun doesn't change all that much throughout the year, nevertheless there are measurable differences in solar heating that result from our planet's slightly elliptical orbit.

Averaged over the globe, sunlight falling on Earth in January is about 7% more intense than it is in July. However, the northern hemisphere of Earth has more land, while the southern hemisphere has more water and that tends to lessen the impact of differences in sunlight between the closest approach and the greatest distance. Sunlight raises the temperature of land more than it does oceans. In July (at aphelion), the land-rich northern half of our planet is tilted toward the Sun. Aphelion sunlight is a little weaker than sunlight at other times of the year, but it nevertheless does a good job warming the continents. In fact, say climate scientists, northern summer in July when the Sun is more distant than usual is a bit warmer than the southern hemisphere summer when the Earth is closer to the Sun.
