The Milky Way is a barred spiral galaxy with a diameter between 100,000 and 180,000 light-years. The Milky Way is estimated to contain 100 -- 400 billion stars. There are probably at least 100 billion planets in the Milky Way. The Solar System is located within the disk, about 26,000 light-years from the Galactic Center, on the inner edge of one of the spiral-shaped concentrations of gas and dust called the Orion Arm. The stars in the inner ≈ 10,000 light-years form a bulge and one or more bars that radiate from the bulge. The very center is marked by an intense radio source, named Sagittarius A *, which is likely to be a supermassive black hole.\n\nBased on this passage, how many planets in the milky way solar system?
Let's be accurate as possible and think first.
at least 100 billion
To answer this question, we should know that: There are probably at least 100 billion planets in the Milky Way.

.

So, the final answer is at least 100 billion
