Total planets in solar system- 8 no.s
Sun :----
Energy produced by nuclear fusion at the Core.
The outer layer of Sun is called Corona. The black marks on the photosphere- Sun spots.
Four hydrogen nuclei(protons) collide to form a Helium nucleus to produce 28 MeV.
Fusion happens at 1.5 Kelvin temperature & 3,40,000 crore Bar pressure.
70 Crore tonne Hydrogen converted to Helium in 1 second.
Hance Bethe discovered fusion energy production at Sun.
Energy produced as Gamma rays & come out of Sun's core after lakhs of years due to its high dense state. By then it's bulk converted into Visible Light, UV, infrared, radio waves.
SoHO- spacecraft send to study the internal structure of the sun called Solar & Heliosperic Observatory. It's a combined effort from European space agency & NASA.
Aditya- India's 1st mission to study Sun will launch in 2017-18.
Sun's travel speed- 618 km/s.
