Planet 9 – History and Location [2021 Update]

It may come as a surprise to many people but the hunt for Planet 9 actually began over a century ago within the ranks of academia. When it comes to Planet 9, many people ask… If there is some huge planet in our solar system, why have astronomers not spotted it visually? Well, it’s not that easy. First, you’ll need a huge telescope (at least 8 meters), then you will need lots of time (we are talking about years and possibly decades), and finally you will need to know what you’re looking for and why.
