Can a brown dwarf star enter our solar system?

The gas giant planet Jupiter is almost big enough to have become a brown dwarf star.

There is no reason a brown dwarf star could not enter our solar system, but there are no stars (dwarf or otherwise) closer than Proxima Centauri, which is about 4.5 light years (25,000,000,000,000 miles) away and not heading this way.

It is possible, the stars are always moving around pulling one each other with there gravity. It is possible for a brown dwarf or any star to get close to the solar system and disrupt the orbit of comets and turn the inner solar system into a shooting gallery.

Now the chances of this happening is very small. But if some thing like that was going to happen we would see it come in decades in advance.

A brown dwarf is a failed star. To be a brown dwarf it need to have 13 Jupiter masses, but not massive enough to cause nuclear fusion.

A Brown dwarf is something between Jupiter and the Sun. The likely hood of one such object just floating through space of its own free will is a huge stretch to being with.

Second a comet is so small that it will have no real influence on Earths Gravity. The moon is a lot bigger than a comet and its a lot closer.

We line up with Jupiter and other planets asteroids and comets all the time no harm comes of it and never will. This theory you heard is based off even worse science than the whole Elien Conspiracy

Matthew: Proxima Centauri is actually a little closer than Alpha Centauri by about 0.2 Light years. But its tiny and almost invisible even to telescopes.

Brown dwarfs are not stars they are failed attempts at being stars and the closest star to the Earth besides the Sun is Alpha Centauri which is 4.3 light years away.

A brown dwarf could be orbiting somewhere between us and nearby stars (it's not a star itself), but the predictions about Nibiru are just attention-seeking rubbish.

Google brown dwarfs.

No, Poxima Centauri is the closest star to our own, it is part of the Alpha Centauri star cluster, it is 4.2 light years distant.

My friend listen ..Yes the dwarf is here . .Just take your cell phone point it at the sun take a few pictures .Look at them ..Its there ,I have many pictures of it.Take the time and try this,it will shock you....Please let me know what you find.You wont need to wonder any more...

It is possible, but it would be very visible in infrared several years in advance. No such evidence to support this wild claim.

If such a body was approaching it would have been visible for decades already.
