If no other non-adiabatic processes occur (like condensation, evaporation and radiation), expansion causes the parcel of air to cool at a set rate of 0.98° Celsius per 100 meters. ... It is the point in the Earth's orbit when it is farthest from the Sun (152.5 million kilometers). Aphelion occurs on the 3rd or 4th of July.

For the year 2001, perihelion will occur on January 3, 2001 and aphelion will occur on July 4, 2001. The actual date for perihelion and aphelion will differ from year to year. But, you can see that the Earth is closest to the Sun in January and farthest from the Sun in July!

I checked all years between 2000 and 2100 for full moons within 24 hours of perigee occurring in the first ten days of July (aphelion always falls on July 3 through 6). By this definition, perigean full Moons near aphelion occur 5 times in this century, in 2004, 2031, 2058, 2066, and 2093. You can search for such events...

The nearest and farthest points in Earth's orbit have special names—the perihelion (literally "near sun") and aphelion ("far sun"). These occur at about the same time each year. Based on your table and the orbit you plotted, determine when perihelion and aphelion occur.

The specific proximal (close) and distal (far) points along Earth's orbit around the sun are called "perihelion" and "aphelion," respectively, and will occur roughly on January 4 and July 4 of this year (these dates progressively change over time as a consequence of the planet's orbital path constantly changing shape.)
