How many solar systems are there in our galaxy?

There are no such things as galaxies in our solar system. Our solar system is a part of galaxy called as milky way,which itself is a part of Virgo cluster and this cluster is a part of observable universe.


The Solar System[a] is the gravitationally-bound system comprising the Sun and the objects that orbit it, either directly or indirectly.Of those objects that orbit the Sun directly, the largest eight are the planets,with the remainder being significantly smaller objects, such as dwarf planets and small Solar System bodies. Of the objects that orbit the Sun indirectly, the moons, two are larger than the smallest planet, Mercury.


The Solar System formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The vast majority of the system’s mass is in the Sun, with the majority of the remaining mass contained in Jupiter. The four smaller inner planets,[c] Mercury,[d] Venus,[e] Earth and Mars,[f], are terrestrial planets,[g] being primarily composed of rock and metal.[h] Asteroid Ceres and trans-Neptunian objects Pluto and Eris.[i] In addition to these two regions,[j] various other small-body populations,[k] including comets
