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.
There are two extremes: Firstly, Earth is furthest from the Sun (aphelion, 152,097,701 km) and Neptune is in opposition (directly opposite the Sun in the sky so that the Earth is exactly between the Sun and Neptune) and nearest to the Sun (perihelion, 4,452,940,833 km). The separation is then 4,452,940,833 km - 152,097,701 km or 4,300,843,132 km.
