Number of stars & planets in Milky Way Galaxy?

Is there any specific numbers on stars & planets count on Milky Way Galaxy ?

• @Hohmannfan Not particularly wishing to start an argument, but what is the purpose of your comment, given that both answers make exactly that same point very clearly? – ProfRob Mar 22 '16 at 10:25

A consensus number is that there roughly $10^{11}$ stars in our Galaxy (though this number is certainly uncertain by a factor of at least two, because it is based on extrapolating what we know about stellar populations in our vicinity). Most of these stars are of lower mass and are much less luminous than the Sun.
