** COOL NERD FODDER ALERT! **

Today we realize that the entire solar system is encased inside an embryo of the Sun called the Heliosphere, outside of which anything else is lost in space, so it's hard to envision any object the size of a large planetary body is hiding inside the Suns Heliosphere but still making regular orbits every 5,000 years. It's not logical when you place the idea in the context of what we know about our place in space and the Milky Way Galaxy we live in. It takes Earth about 260 million years to make one galactic orbit. Planet X would have to be inside the Sun's Helioshpere in order to be orbiting, and if it's outside of the Heliosphere it cannot be worth considering as a regular visitor, but rather a freak passing recorded somewhere in the past, which was probably not a planetary body, just seemed like it was.
Heliosphere - Wikipedia

The combined speed of our star and our solar system exceeds a half million miles per hour when all the angular trajectories are accounted for, which is about six of them all told. So many factors are against the idea of hidden planet that another explanation is needed if the idea is be given any credence at all.

There would also be evidence of such things happening every 5,000 years if it did have a regular frequency of an orbit.

Wasn't that the Yucatan impact that killed the dinosaurs ? So whats the biggest ? Is that the one in Egypt ?

There are some unconfirmed ones over 300 miles across.......so as cool as the one in Arizona was to see it is very very small.

Glad I won't be around to see it.


Estimates of 2010 WC9's size range from 60 m to 130 m wide. This puts it in the class of the Tunguska impactor, which leveled a forest in Siberia in 1908. And it is at least 3 times as large as the Chelyabinsk meteoroid, which exploded in the morning sky over Russia on Feb. 15, 2013, shattering windows and knocking people to the ground

There's no danger of a collision this time, though. Analysts are certain 2010 WC9 will not hit Earth--neither this week nor in the foreseeable future. New observations of the asteroid in recent days have extended our knowledge of its orbit and eliminated it as a threat for at least the next 100 years.
