The Earth is as farthest as it could be from on Monday

Every year, around two weeks post the Summer Solstice, the distance between the Sun and The Earth is maximum. The moment is also called as aphelion, appears at 6:27 pm EDT on Monday, while the distance between the Sun and The Earth is around 94.5 million miles.

The event occurs as the orbit of The Earth is prolonged into a little elongated ellipse.

The impact on weather

It appears totally opposite that Earth is farthest away from the Sun at some point in the summer and nearest in the winter. However, the distance doesn’t really affect the amount of energy transmitted by the Sun, which is around 1.361 kilowatts per square meter.

The number shows a minimum fluctuation and the scientists call it as the solar constant.

Sun’s angle is the origin of the seasons

Summers are hotter in comparison with the winters due to Earth’s tilt, around 23.44°. This factor is the reason the Sun is slightly higher in the sky in summer days, focusing more of its energy into a targeted area, generating more heat. The lower angle of Sun during winters spread its energy over wider area, reducing the temperature on the area.

During summer days the Sun spends extra time over the horizon, which causes us to receive more direct rays for longer period. On the contrary, it spends lesser time over the horizon in winter resulting into lesser heat radiation and longer nights.

All the things regarding seasons are related to the hemisphere of course. The majority fraction of the Southern hemisphere is covered with water. Water has high capacity of heat and more amount of heat is required to increase its temperature than land.
