What is the biggest galaxy or solar system?

Answer 1

Probably not. Our solar system has 8 planets, which is the largest number of confirmed planets in any known system. There is, however, the system orbiting the star HD10180, which as at least 7 planets, possibly as many as 9. This is at a time when we have discovered about 1200 other planetary systems, out of an estimated 100 to 400 billion in our galaxy. The easily leaves room for systems with more than 8 planets. Even the known planetary systems may have other planets that we cannot detect with current technology.

Answer 2

Our solar system is part of the galaxy. Our galaxy (the milky way) is much larger than the stand alone solar system, its a group of 200 billion or so different solar systems.

IC 1101 is a lenticular galaxy that has a diameter of approximately 5.5 million light years, which makes it the largest known galaxy in terms of breadth. It roughly contains 100 trillion stars and is more than 50 times the size of the Milky Way and 2000 times as massive

Answer 3

Probably galactic filaments. The largest known structure in the observable Universe is the Sloan Great Wall at a length of around 1.37 billion light years.

Answer 4

The largest structures in the known universe include the large quasar group.

Answer 5

Inner core magma
