Scientists speculate that there may have been a 5th giant planet in our solar system. Do you find this as cool as I do?

Neat. Would have liked to have seen this possible collision...from a safe distance, of course.

Our Solar System May Have Had A Fifth 'Giant' Planet

It is plausible. "Planet X" and rogue star theories for comet and asteroid orbital eccentricities have been around for a long time. The researcher appears to have come up with a model that is reasonably accurate. Very interesting piece.

Did you know you could fit all the planets in our solar system side by side and it would fit between the earth and moon?

This is pretty cool. I have always found the solar system fascinating and the recent images of Pluto have peaked my interest once again. To think there was a fifth giant gas planet is awesome.

Way cool. Didn't know about this. Video no longer available, 2019, but I googled it. Some connections to info about the 5th planet.
