Is any planet bigger than the Sun?

Explanation: To begin with planets, as that is the easiest question to answer, there are no planets bigger than the Sun or even close to the size of the Sun. Logically, then the largest planet by mass could only be about 12 times the mass of Jupiter. The Sun has about 1000 times the mass of Jupiter.

Is universe bigger than Galaxy?

Galaxies come in many sizes. The Milky Way is big, but some galaxies, like our Andromeda Galaxy neighbor, are much larger. The universe is all of the galaxies – billions of them! Our Milky Way Galaxy is one among the billions of galaxies in our Universe.

Is a star bigger than planet Earth?

Yes! In fact, most stars are bigger than the Earth. The diagram below compares the size of our sun with the sizes of the other planets in our solar system. The sun is much bigger than the Earth, and it isn’t even a particularly large star.

Is Jupiter the smallest planet?

So I’ll leave it up to you whether you believe Mercury or Pluto is the smallest planet in the solar system. Jupiter, however, holds the largest planet distinction firmly….The Largest Planet In The Solar System – Jupiter.
