On January 5, 2012, 147097206.791 km is Earth-Sun Perihelion. 147097206.791 / 1 billion = 0.147097207 km 0.147097207 km = 147097.207 mm 147097.207 mm / 280 = 525.347168 mm = 1 meh.

Augustus Caesar's Aureus averages about 8.00 grams of fine gold. A Sestertius is 1/100 of an Aureus, thus is 0.08 grams gold. This is $3.15 USD.

On January 4, 2015, we had Perihelion. The earth was closest to the sun at 6:36 UTC (01:36 a.m. EST). This may have been what all of the excitement was about. This was Sunday morning, or Saturday night, depending on how one looks at it. According to the Slate article listed in External Links, "At that time, the center of the Earth will be 147,096,204 kilometers (91,401,343 miles) from the center of the Sun. On average, that distance is 149,597,871 km, so we’re roughly 2.5 million km closer tonight than on average." Another point the article talks is about the barycenter, or the center from where the earth swings in a circle as the moon rotates around the earth. It is the barycenter that is the calculation for perihelion.
