what does the center of this way consists of?
In the inner few kpc (around 10,000 light-years radius) is a dense concentration of mostly old stars in a roughly spheroidal shape called the bulge

how many star are there in milky way galaxy It is estimated to contain 100–400 billion stars what is the milky way? It  is the galaxy that contains our Solar System, with the name describing the galaxy's appearance from Earth who was the first to discover this system? Galileo Galilei can you name some things that this system consists of? Sun,  eight planets small Solar System bodies, moons what is the size of the way? It is approximately 890 billion times the mass of the Sun.

Milky Way [SEP] Galactic Center
The Sun is from the Galactic Center. This value is estimated using geometric-based methods or by measuring selected astronomical objects that serve as standard candles, with different techniques yielding various values within this approximate range. In the inner few kpc (around 10,000 light-years radius) is a dense concentration of mostly old stars in a roughly spheroidal shape called the bulge. It has been proposed that the Milky Way lacks a bulge formed due to a collision and merger between previous galaxies, and that instead it only has a "pseudobulge" formed by its central bar. However, confusion in the literature between the (peanut shell)-shaped structure created by instabilities in the bar, versus a possible bulge with an expected half-light radius of 0.5 kpc, abounds.
