Question

Diameter of Sun is _______.
A. 12 lakh km
B. 13 lakh km
C. 14 lakh km
D. 15 lakh km

Answer 1

Hint:Its diameter is 864,000 miles or so, 109 times the earth's diameter.
The sun's mean radius is approximately 7 lakh kilometres.

Complete answer:
At the core of the solar system, the sun is a hot ball of hydrogen and helium. It has a circumference of 864,000 miles (1,392,000 km), which makes it 109 times larger than Earth.
The size of the Sun relative to the largest known stars (red giants) is not very high. However, relative to the most common type of star in the universe, the red dwarf, the Sun is a little larger. So the Sun is not the largest type of star in the universe, but it is certainly larger than most.
As far as the mass of the Sun is concerned, relative to other bodies found in our solar system, the Sun is easily the most massive. The Sun alone comprises 99.8% of the total mass in the Solar System.

Hence the correct answer is option C.

Note:The sun has a diameter of 1.4x109m and a distance of 1.5x1011m from the earth.
Within the Sun, more than a million Earths could fit. Sun travels at 220 km/s
