Milky way is

The nearest galaxy to our Milky ways is

The diameter of Milky Ways is over ----- light years.

Let us assume that our galaxy consists of 2.5×10^11 stars each of one solar mass. How long will a star at a distance of 50,000 ly from the galactic center take to complete on revolution? Take the diameter of the Milky way to be 10^5ly .

Let us consider that our galaxy consists of 2.5xx10^(11) stars each of one solar mass. How long will this star at a distance of 50,000 light year from the galastic entre take to complete one revolution? Take the diameter of the Milky way to be 10^5ly. G=6.67xx 10^(-11) Nm^(2) Kg^(-2). (1 ly= 9.46xx10^(15)m)
