SOLAR SYSTEM - STATISTICS
The solar system consists of the Sun and 9 planets revolving around it in different orbits. The statistics of the sun and the planets are given below :
SUN Age : About 5 Billion years
Distance : 149.8 Million Kms
Diameter : 1,38,400 Kms.
Photosphere temperature : 5,770 K
Core temperature : 150,000,000 K
Absolute visual magnitude : 4.75
Rotation (as seen from the earth at the equator) : 25.38 days
Rotation (near the poles) : 33 days
The sun consists of 71% of Hydrogen, 26.5% Helium and 2.5% of other elements. The rays of the Sun take about 8 minutes to reach the earth.
