Question: Is there more planets than we think?

David Sobral answered on 19 Mar 2020:

There are at least 100 billion planets in our galaxy alone. That’s because in the last few years we learnt that there is at least one planet per star and there are soooo many stars! It’s incredible how many planets are yet to be discovered, and they come in all sorts of sizes and orbit all kinds of stars!

It turns out that the most common types of planets are just a big larger than the Earth and the most common of them all are like Neptune!
