Quote of the day: ORBIT

July 5, 2012


July 5 is the aphelion, the point in the year when the Earth is at its farthest distance from the Sun. The Earth and all the other planets have orbits that are “eccentric,” a slightly squashed circle, and the Sun is slightly closer to one end of the ellipse. The perihelion — the point in the orbit when we’re closest to the Sun — occurs in January, and at that time we’re about 5 million kilometers closer than we are at aphelion in July.
