What is the biggest star in our solar system?
the sun
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.
Is there a triple star system?
Three-star systems are uncommon, but not rare. NASA estimates that around 10 percent of the roughly 7 billion star systems in our galaxy have three stars. What is rare is for a triple-star system to also have protoplanetary disks. Things only got weirder from there.
How many stars can be in a star system?
A majority have at least two stars(binary). A system could theoretically have an unlimited amount of stars. Systems with up to six stars have been observed. Now, a little more about the theoretical companion star within our our solar system.
Which star is bigger than Sun?
Mu Cephi – about 1500 times the size of our sun. Betelgeuse – about 900 times the size of our sun. Antares – about 530 times the size of our sun. Deneb – about 145 times the size of our sun.
Is star a solar system?
Our solar system is just one specific planetary system—a star with planets orbiting around it. Our planetary system is the only one officially called “solar system,” but astronomers have discovered more than 3,200 other stars with planets orbiting them in our galaxy.
Are there any triple-star systems?
Three-star systems are uncommon, but not rare. NASA estimates that around 10 percent of the roughly 7 billion star systems in our galaxy have three stars. What is rare is for a triple-star system to also have protoplanetary disks.
