- Sun -

The Sun started to burn Hydrogen to Helium around 4.600.000.000 years ago.
Or does the Sun burn iron?

Temperatures:
Core 15.000.000°C > Photosphere 6.000°C > Chromosphere 50.000°C > Corona over 1.000.000°C

Diameter 1.390.000 kilometres.


Earth is closest to Sun on January 2 (perihelion).
Earth is farthest away from Sun on July 2 (aphelion).

- EARTH -

Earth was formed around 4.500.000.000 years ago.

Diameter ~ 12.756 kilometres equatorial, ~ 12.713 km poles.

Perihelion year  365,259636 days
Siderial year    365,256366 days
Tropical year    365,242199 days

On Earth live an estimated 5.000.000 species. 
The number of species is decreasing. 
The highest number of species are among insects, 
fungi and worms living in the ocean sediments.

Fossilized remains of early organisms have been found in 
sediments that appear to be around 3.500.000.000 years old.

- Asteroids and Comets -

An estimated one in six of the big near-Earth asteroids may be actually
two asteroids orbiting each other. This can result in a double hit.
A double system circling around a common axis is more difficult to engage
and increases prediction complexity.
