Question

What is bigger: the sun or the earth?

Answer 1

Hint: There are a total of eight planets in our solar system. As the question is to find the bigger celestial object, that is either the sun of the earth, so, in terms of the radius, we will compare the planet and the star. The celestial object with a bigger radius will be the bigger body.

Complete answer:
There are a total of 8 planets. They are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Among these planets, Mercury is the smallest planet in our solar system and Jupiter is the biggest planet in our solar system.
The diameter of the sun is 1,392,000 km in diameter. The diameter of the planet Earth is 12,756 km. The diameter of the sun is almost 109 times more than the diameter of the planet earth.

Additional information:
The radius of the planet Earth in terms of km is 6,378 km. The radius of the planet Mercury in terms of km is, 2,440 km, about one-third the size of the planet earth. The radius of the planet Venus in terms of km is, 6,052 km, slightly smaller than the planet earth. The radius of the planet Mars in terms of km is, 3,397 km, about half the size of the planet earth. The radius of the planet Jupiter in terms of km is, 71,492 km, about 11 times the size of the planet earth. The radius of the planet Saturn in terms of km is, 60,268 km, about 9 times larger than the size of the planet earth. The radius of the planet Uranus in terms of km is, 25,559 km, about 4 times larger than the size of the planet earth. The radius of the planet Neptune in terms of km is 24,766 km, only slightly smaller than the planet Uranus.
$$\therefore$$The sun is bigger than the earth.

Note:
The arrangement of the planets in their decreasing sizes is given as follows. Jupiter > Saturn > Uranus > Neptune > Earth > Venus > Mars > Mercury. There are no other parameters using which the size of the planet can be compared, so, we have used the parameter radius.
