what is the biggest star in our solar system？
ANSWER: The largest star, and indeed the only star in our solar system, is the sun. The sun is a bit under a million miles across. About 110 Earths put side by side would equal the size of the sun. The sun has 99.8 percent of the mass of our solar system.2014年2月19日
Keeping this in consideration,What is the biggest star in our galaxy?
Answer: The largest known star (in terms of mass and brightness) is called the Pistol Star. It is believed to be 100 times as massive as our Sun, and 10,000,000 times as bright! In 1990, a star named the Pistol Star was known to lie at the center of the Pistol Nebula in the Milky Way Galaxy.
Furthermore,Is sun a biggest star?
The Short Answer: Our Sun is an average sized star: there are smaller stars and larger stars, even up to 100 times larger. Many other solar systems have multiple suns, while ours just has one.

Yes, VY Canis Majoris of the constellation canis major is larger than UY Scuti and is the biggest star ever discovered by man. That honor goes to R136a1, which weighs in at about 300 times the mass of the sun but only about 30 solar radii.
Proxima CentauriDistance Information Proxima Centauri, the closest star to our own, is still 40,208,000,000,000 km away. (Or about 268,770 AU.)
Blue starsWhite stars are hotter than red and yellow. Blue stars are the hottest stars of all. Stars are not really star-shaped. They are round like our sun.
Sirius, also known as the Dog Star or Sirius A, is the brightest star in Earth's night sky. The name means "glowing" in Greek — a fitting description, as only a few planets, the full moon and the International Space Station outshine this star. Because Sirius is so bright, it was well-known to the ancients.
the Hercules-Corona Borealis Great WallThe biggest single entity that scientists have identified in the universe is a supercluster of galaxies called the Hercules-Corona Borealis Great Wall. It's so wide that light takes about 10 billion years to move across the entire structure.
Researchers dubbed this the eXtreme Deep Field. All in all, Hubble reveals an estimated 100 billion galaxies in the universe or so, but this number is likely to increase to about 200 billion as telescope technology in space improves, Livio told Space.com.
