If you thought that Pluto was the gatekeeper of the outer edge of our solar system, your knowledge might need a massive update. Aside from comets that routinely orbit, and sometimes get too close, to our sun, there are a whole host of space objects beyond the little minor planet. And one of them might even be a planet in its own right. That is the discovery announced by Scott Sheppard of the Carnegie Institute of Washington last November 10. Simply called V774104, it is considered to be the most distant object in the solar system currently known.
