Bimodal IT is the practice of managing two separate, coherent modes of IT delivery, one focused on stability and the other on agility. Mode 1 is traditional and sequential, emphasizing safety and accuracy. Mode 2 is exploratory and nonlinear, emphasizing agility and speed.
Earth is closest to the sun every year in early January, when itâs winter for the Northern Hemisphere. Weâre farthest away from the sun in early July, during our Northern Hemisphere summer. Earth is about 3 million miles (5 million km) closer to the sun in early January than it is in early July. Thatâs not a huge change in distance. Itâs not enough of a change to cause the seasons on Earth. On January 4, 2017, Earth at its closest point swings to within 91,404,322 miles (147,100,993 km) of the sun.
Sometime in August, our planet reaches it's closest distance from the sun (Perihelion) with a distance of about 0.98 AU. Here, AU is short for Astronomical Unit which is defined as earth's average distance from the sun.
