Detailed explanation-1: -The Universe is the biggest and contains billions of galaxies. A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems, all held together by gravity.
Detailed explanation-2: -The solar system has a diameter more than 40 times greater than the distance to the sun, but the solar system is a tiny part of much larger galaxy. Our galaxy (Milky Way) is only one of billions of other galaxies in the universe.
Detailed explanation-3: -The Milky Way is big, but some galaxies, like our Andromeda Galaxy neighbor, are much larger. The universe is all of the galaxies – billions of them! NASA’s telescopes allow us to study galaxies beyond our own in exquisite detail, and to explore the most distant reaches of the observable universe.
