Sirius

Sirius is the biggest planet in our universe. It is twice the size of our sun! Jupiter (the largest planet in our solar system) is smaller than Wolf 359 which is smaller than our sun which is half the size of Sirius, the largest planet in our universe, I say our universe because there may be more than just one universe! If Sirius crashed into Earth, it would be like an atom hitting your face. A serious accident for us!
