Angular size: 31.6–32.7 minutes of arc
Mean radiance (Isol): 2.009×107 W·m−2·sr−1
Luminosity (Lsol): 3.828×1026 W; ≈ 3.75×1028 lm; ≈ 98 lm/W efficacy
Age: ≈ 4.6 billion years
Answer :-
•The size of the sun is 6.09 × 10 ¹² km² of the surface area of the sun which is 12000 times the size of the Earth.
•The surface temperature of the sun is 57K and it's core temperature is 15 Million Centigrade.
•The sun formed approximately 4.6 billion years ago. It is present at the centre of our solar system.
•Hydrogen and Helium are two of the major gases from which the sun is composed of.
•By Nuclear fusion, Hydrogen is converted into helium which produces large amount of heat and light.
