Space is one of the last unexplored frontiers. Astronomers are constantly making new discoveries, helping us to better understand the cosmos. For years now there's been speculation that there's a huge planet in our solar system, with astronomers and scientists saying that this celestial body is affecting everything within our solar system. One of the issues they've faced is trying to pinpoint where this object is. However, back in 1983 astronomers said they brushed over data that could have revealed this mysterious planet. It's been estimated that this object was seen over 20 billion miles away.
