'8##When is the sun closest to the earth in the Northern Hemisphere?++none$$summer%%fall^^spring &&winter@@@$One of the biggest misconceptions in science is the idea of seasons being a result of the distance of the sun to earth. Remember the interviews with the Harvard graduates in A Private Universe? In that documentary, glaring misconceptions about basic science concepts became more public. !!',
'9##When the sun is closest to the earth, it is called what?++none$$eclipse%%aphelion^^perihelion&&@@@$Earth travels around the sun in an elliptical orbit. That means the sun varies in distance from the earth from about 147.5 million km to about 152.6 million km in July. With most science textbooks demonstrating the oval like shape of the orbit, many people have come to believe that the Northern Hemisphere experiences summer when the sun is at its closest point. Part of the problem is the exaggeration of the orbits printed in textbooks. In reality the earth is closest to the sun on about January 4th.!!');
