The day of the year when the Earth is farther from the Sun

There was the phenomenon known as aphelion , which occurs each year between March and July 5. This means it is the day of the year when the sun is farthest from Earth.

Although visually it is imperceptible, with a special telescope experts can see that the sun looks smaller. Precisely, is 3 percent less than its normal size.

According to experts, the effects of this are changes in the tides and a possible decrease in solar energy , but has no effect on the climate, or severity of the Earth.

For example, in 2007 in Buenos Aires aphelion coincided with a rare snowfall, the first in a century in Argentina's capital. But both processes had had nothing to do.
