On 5 July 2019 at 00:10 the Earth reached the point of its orbit furthest from the Sun, called aphelion, reaching the distance of 152,104,285 kilometers from its star.
It happened about 2 weeks after the summer solstice, which took place on June 21st .
“The Earth’s orbit is almost circular, so it is not the distance from the Sun that determines heating or cooling, but rather the inclination with which the solar rays affect the earth’s atmosphere”, explains Mauro Messerotti, of the Trieste Observatory of the National Institute of Astrophysics (Inaf) and of the University of Trieste.
In the Northern hemisphere the inclination of the solar rays “is minimal in this period and this determines the summer. As proof of this – he concludes – the Earth has reached the point of its orbit closest to the Sun on January 3, 2019, when in the ‘Northern hemisphere was full winter’.
