How many stars are in the milky way?
https://en.wikipedia.org/wiki/Milky_Way
The Milky Way contains between 200
and 400 billion stars and at least 100 billion planets. The exact figure
depends on the number of very-low-mass stars, which are hard to detect,
especially at distances of more than 300 ly (90 pc) from the Sun.
Oldest known star: ≥13.7 Gyr
Bar pattern rotation period: 100–120 Myr
Number of stars: 100–400 billion (2.5 × 1011 ± ...
Mass: 0.8–1.5×1012 M☉

Jul 22, 2015 - There are different
models for estimating the number of stars in the Milky Way and the answers they
give differ depending on what is used as the average mass of a star. The most
common answer seems to be that there are 100 billion stars in the Milky
Way on the low-end and 400 billion on the high end.
