- my teacher said this was the wrong answer but she never taught us that it was like that
- she says we are farther away because the axis is pointed away from the sun!!!
Sometime in February, our planet reaches it's farthest distance from the sun (Aphelion) with a distance of about 1.02 AU.
Sometime in August, our planet reaches it's closest distance from the sun (Perihelion) with a distance of about 0.98 AU.
Here, AU is short for "Astronomical Unit" which is defined as earth's average distance from the sun.
Thus 1 AU = 92.956×106 miles = 149.6×106 km
However, if we consider the earth as being a perfect sphere, and track the point on earth's surface that is closest to the sun, then it is a totally different matter. If you stand at this point, the sun will be directly above you in the sky.
Summer solstice = The moment when this point is furthest north.
Winter solstice = The moment when this point is furthest south.
Vernal equinox = The moment this point crosses the equator from the South to the North.
Autumnal equinox = The moment this point crosses the equator from the North to the South.
