How far away from the sun are we during the four seasons?
Spring: 149.6 million (M) km to 152.1 M km. Summer: 152.1 M km to 149.6 M km. Fall: 149.6 M km to 147.1 M km. Winter: 147,1 M k, to 149.6 M km.
The starting and end dates for the seasons are 21 or 22 or 23 of the respective month.
Significantly, they start at equinox/solstice and end at solstice/equinox.
At the start of Spring on (vernal or March) equinox, the Earth is at distance of about 1 AU = 149.6 million (M) km, from the Sun. Spring ends on summer (June) solstice. The Earth is then near aphelion = 152.1 M km.
