I have a few questions about Planets, and astriods.

Why doesn't NASA just send a probe out to see if Planet Niribu X really exists? If a Astriod of metor was heading towards Earth, could NASA probably shoot it down or something like that? If a huge meteor hit Jupiter, would it have no effect what so ever sense Jupiter is a gas Giant?

1. To send a probe just to prove that planet Nibiru (or Planet X) exists is just a foolish idea to them. It will be caught in their radar anyway, if it comes close enough.

2. Now for this question, there is a group of scientists... i just can't recall the name. Anyway, they are working on statistical evidence and through radar sensor and stuff, to detect asteroids that are coming close to us. There are a number of ways that they offer NASA to do if by any chance a meteor does come in our way. (And the chance is way, way higher than we all think!)

For immediate response (if we only have like a couple of months or weeks), we can nuke the meteor so that it will burn into fragments and the fragments will burn in the atmosphere.

We could tow it away, using like strong electromagnetic or strong wind currents, this will probably take like a year, at the least

We could attach a rocket to it and send it flying to Mars or something like that! (also takes a year)

An odd option is to create a parabolic mirror which can reflect sunlight and heat to the meteor to melt it and stuff. (also takes a year)

But all those are only for huge meteors small ones will usually be burned in the atmosphere.

3. Yes there will be no effects, well there must be a type of change but not major changes. Besides the planet is very large and strong!

There is no proof that Planet Niribu X exist. It could be just a story that you can used to write an interesting book or make an exciting movie.

Here are some evidence or logic of its non existence:
1. All claims of its existence have been proven to be false and deceitful.
