THE EARTH AT APHELION:
On the 4th of July, the Earth was farther from the sun than at any other time of the year. Earth's orbit around the sun is not a perfect circle, it's an ellipse, and on July 4th, Earth was at the end of the ellipse farthest from the sunAstronomers call this "aphelion." When we are at aphelion, the sun appears slightly smaller in the sky (by about 1.7%) and global solar heating is actually a little less (by about 3.5%) than the yearly average. This provides little relief from the summer heat, however. Average temperatures in July in the Ozarks are around 90 degrees for highs and 67 degrees for lows. The hottest temperature recorded in July at Springfield, Missouri was 113 degrees back on the 14th of July 1954. On that same day Warsaw, Missouri recorded a high temperature of 118 degrees, which stands today as the record high temperature for the state.
