Question

How many known planets are in the Milky Way?

Answer 1

Hint :The Milky Way is the galaxy that contains our Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye.

Complete Step By Step Answer:
Our solar system is just one specific planetary system—a star with planets orbiting around it. Our planetary system is the only one officially called “solar system,” but astronomers have discovered more than 2,500 other stars with planets orbiting them in our galaxy. That’s just how many we’ve found so far. There are likely to be many more planetary systems out there waiting to be discovered!
Our Sun is just one of about 200 billion stars in our galaxy. That gives scientists plenty of places to hunt for exoplanets, or planets outside our solar system. But our capabilities have only recently progressed to the point where astronomers can actually find such planets.

Note :
The number of planets discovered isnt fixed. This is because the scientists are finding different celestial bodies on a regular basis. The technology to identify and mark planets has only advanced a few years ago and is still new. In the coming years there will be so many more planets that will be added in the list of identified planets.
