This Friday, July 6 at 6:00 pm, the Earth was farther away from the Sun than any other day of this year. That is, he reached his aphelion, which means precisely "far from the sun".
The Astronomical Observatory of Lisbon explains that although our star remains of the same size, the sun also seems smaller "because its apparent (angular) diameter has reached the minimum value: 31.46 & # 39;
The average distance from Earth to the Sun is about 150 million kilometers, but given the Earth's elliptical orbit, the distance varies daily, reaching its maximum – 152 million kilometers – and in January its minimum – 147 million – when perihelion occurs
Aphelion occurs annually between July 2 and 7. This year's perihelion was recorded on January 3.
The greatest distance from the sun also results in a lower orbit rate, according to Kepler's law, which explains that when the planets are close to the Sun, they move faster
OAL remembers, in the case where we are astonished at the most great distance from the sun in summer, that "the seasons of the year"
does not depend on the distance to the Sun (which varies little because our elliptical orbit is almost circular) but rather of the slope of the Axis of the Earth in relation to its orbital plane. "
