As you mention, there are similarities between spiral galaxies and of galaxies and what they can teach us about dark matter in the universe. Many people are not clear about the difference between our Solar System, our Milky Way Galaxy, and the Universe. Let's look at the basics. Our Solar System. It is the 5th largest planet, in the solar system, and has a radius of 6, km at The largest known galaxy, IC , has over trillion stars.

To understand the solar system, one should know the definition of a star system. A star system is a system in which planets orbit around a massive star.

This is due to the gravitational attraction that is present in between them. A solar system is a specific kind of star system in which the Sun is at the centre. The solar system consists of anything that orbits the sun or orbits the planets which orbit the sun.

The moon of earth, for example, is a part of our solar system. A galaxy, on the other hand, is a huge collection of stars that are held together by gravitational attraction. There can be a million to over a trillion stars within a galaxy. It consists of interstellar gas, star clusters and numerous star systems. Many star systems can be part of a single galaxy but not the other way around.

Perhaps the biggest difference between a solar system and a galaxy is their size. While the solar system is just a light year across, a galaxy is typically up tolight years in length. One light year means that it takes light one year to travel this distance. The analogy of the composition of the solar system and a galaxy can be drawn by imagining a gigantic piece of paper with hundreds of millions of dots on it.

The solar system would be a single dot on such a paper, where as Milky Way, the galaxy in which the solar system resides, would constitute all the dots on the paper. Galaxies usually have a massive black hole at its centre.

However, there is no black hole present at the centre of the solar system. In fact the solar system cannot accommodate such a massive thing within it. Galaxies consist of dark matter.

Solar System Solar systems are the smallest of the three systems in question. A solar system consists of a star, such as the sun, and the objects affected by its gravity. These objects include planets, moons, asteroids, comets and meteoroids. Although solar systems are smaller than either the universe or a galaxy, the actual size of even the very smallest of solar system is difficult for the human mind to truly comprehend.

In terms of scale, if the sun had the dimensions of a tennis ball, the Earth would be the size of a grain of sand located about 8 meters 26 feet away. Star-Filled Galaxies A galaxy is a system of solar systems and other stars.

Difference between Galaxy and Solar System

Galaxies, like solar systems, are held together by gravity. In galaxies, the solar systems are separated by vast sections of mostly empty space. The galaxy that contains the Earth and its solar system is called the Milky Way.

This galaxy is thought to contain more than billion different stars. Solar systems orbit around their galaxies just as planets orbit around their suns.
