what is the size of sun?

Answer 1

The sun is approximately 865,400 mi (1,392,000 km) in diameter, and its volume is about 1,300,000 times that of the earth. And total mass of the Earth, and occupies a volume of 1.386 × 109 km³.

So you can calculate yourself ie. 1.386 × 109 km³. x 1,300,000 -
I am little weak in calcultions, so I have given the work to you. -

Ref:- The mass of the oceans is approximately 1.35 × 1018 tonnes, or about 1/4400 of the total mass of the Earth, and occupies a volume of 1.386 × 109 km³. If all of the land on Earth were spread evenly, water would rise to an altitude of more than 2.7 km (approximately 1.7 mi).[47] About 97.5% of the water is saline, while the remaining 2.5% is fresh water. The majority of the fresh water, about 68.7%, is currently in the form of ice. (as per - http://www.answers.com/earth?cat=health )

The sun is approximately 865,400 mi (1,392,000 km) in diameter, and its volume is about 1,300,000 times that of the earth. Its mass is almost 700 times the total mass of all the bodies in the solar system and 332,000 times that of the earth. (As per - http://www.answers.com/sun?cat=technology)-

Answer 2

The sun is closer to the earth than is any other star, and so it looks larger than other stars. Compared with the planets in the solar system, the sun is large. For e.g, the diameter of the sun is about 1,392,000 km. This distance is about 109 times the diameter of the earth. The sun's diameter is also 10 times the diameter of Jupiter, the largest planet, and is about 400 times the diameter of the moon.
Compared with other stars, the sun is only medium - sized. In fact, it is one of the many stars that astronomers call yellow dwarfs. Some stars is 1/10 of the sun whereas others are 1000 times bigger than it.

Answer 3

Since the sun is entirely gaseous, it doesn't have an actual
"surface" like the Earth; however, we usually measure the
"photosphere" which is the region where the light is given
off. The diameter of the photosphere is about 1.38
gigameters (a gigameter is a billion meters) which is about
864,000 miles. As others have mentioned, you could fit
more than 1,200,000 Earths into this volume and still have
enough room left over for a few Jupiters!
And remember, our sun is just an average-sized star!
Hope this helps.
