The Earth

An Exceptional Planet

With elaborate research endeavors astronomers are searching for other planets in different star systems. Among all previously found planets and exoplanets no other earthlike planet has been found so far.

Physical, chemical and astronomical conditions on our home planet offer us a set of unique living conditions. Below is a list of 12 scientific features that impact our thoughts about the origin of the earth.

Necessary conditions for
the habitability of the earth

1. The correct distance from the sun: We are moving around our central star with a distance of approximately 90 million miles (150 million km).The amount of light and heat radiated by the sun and the earth’s distance to the sun are fine tuned in such a way that the temperatures on earth vary mostly between 32 °F and 100 °F (0 °C and 40 °C). These are exactly the narrow limits required to sustain the biochemical processes in of the body cells and thereby create the optimal conditions necessary to maintain life — especially human life.

2. The correct speed of rotation of the earth: If the earth’s rotation around its axis were considerably slower, then the temperature differences between night and day would be extreme. Temperatures would climb to intolerable heights during the day because of the prolonged influx of heat, and the surface would be dried out. On the
