As a result of the close relationships between the four these dimensions of sustainable development, achieving this goal requires a dynamic balance between: 1  Production and consumption; 2  Ecology and economics; 3  Development and conservation; 4  Culture and ecology; and. 5  Democracy and economics.
The closest bright star to the north celestial pole is Polaris. At magnitude 1.97 (variable), it is the brightest star in the Ursa Minor constellation (at the end of the handle of the Little Dipper asterism). As of October 2012 its declination is +89Â°19â²8â³ (at epoch J2000 it was +89Â°15â²51.2â³).t is consequently known as Polaris (from Latin stella polaris pole star). It was formerly sometimes known as Cynosura, from a time before it was the pole star, from its Greek name meaning dog's tail (as the constellation of Ursa Minor was interpreted as a dog, not a bear, in antiquity).
If you followed this axis out into space from the northern hemisphere on Earth, it would point toward a particular star in the sky. We call that star the North Star since it sits in the direction that the spin axis from the northern hemisphere of Earth points. At present, the star known as Polaris is the North Star. However, Polaris has not always been the North Star and will not always be the North Star. To understand that, we need to look at how the Earth spins on its axis. The spin axis of the Earth undergoes a motion called precession.
