Well a Brown Dwarf is coming! That I do know and its in most of our lifetimes. It passed pretty close to us in 2010 and it will be even closer on its way back out. (Way to close). In 2010 we had the moon or earth get completely yanked out of whack along with the massive quake in Japan and a few other large ones. A lot of people seen the moon or earth getting pulled so bad the man on the moon showed it well.
Today native Indian tribes will state on the record that the stars are not where they should be as they can not navigate by them anymore and the seasons have changed so that tells its earth that is getting pulled on so much its tilting more.

A Brown Dwarf is made mostly of Iron (Oxide Rust)
More precisely, a brown dwarf is a massive ball of hydrogen, helium, and trace amounts of metals that is not massive enough to burn hydrogen, but is massive enough to burn deuterium.
The only way earth will get any advanced warning is with an Infra Red telescope.
When the big quakes start up again pay close attention to the moon, when it does not look right

Please show us proof that the proper and radial motion of this star is consistent with the Sagittarius dwarf.
I DID check out the links I Posted !
No, that does not prove that the proper and radial motion of this star is consistent with the Sagittarius dwarf. Yes, I know what a "rogue planet" is. Do you know what the proper and radial motions of a star are?
Proper Motion and Parallax Were it not for the motion of the Earth around the Sun, proper motion would lead to a simple drift of the position of a star on the celestial sphere in a particular direction. However, because of the motion of the Earth on its orbit, there is a parallax effect for stars that are near enough to exhibit significant proper motion that causes the star to execute motion in a small ellipse on the celestial sphere over a period of a year (this ellipse is just a mirror of the actual motion of the Earth on its elliptical orbit).

No, you apparently don't even know what a rogue star is. Yes, the motion does show where it came from and where it is going. A rogue star is one whose velocity is at or above galactic escape velocity, but the velocity vector still tells you where it came from and where it is going. So by all means, prove to us that this star's velocity vector indicates it "escaped from" the sagittarius dwarf. I'm getting tired of asking you and you not answering. Handwaving to the existence of the sagittarius dwarf passing near our section of the galaxy does not prove what I'm asking you.
Stars with really tiny radial velocities and tiny tangential motions may be scientifically interesting, however, as such velocities are what you'd expect for "solar siblings" (i.e. stars that would have shared the Sun's same birth cluster) - but this is getting off topic. Scholz's star is certainly not such a star, as it is moving ~83 km/s with respect to the Sun.

And for those where English is a second, third or fourth language (or first) it's ROGUE star... a rouge star would have lipstick or blush applied.
And again, anyone more versed in planetary physics know what the article meant when it said although no direct observation was possible, em effects might have be seen with a naked eye?
A flair up? Our sun's reaction? Auroras? I can't figure that out...

So Obviously you Claiming you Do you Tell US !

If something like this were to occur again, I think it would be an efficient method of Interstellar travel, by hitching a ride and colonizing a planet of a solar system that was passing by nearby and do the same thing again when another star has a close encounter of that solar system.

There is no data to suggest that it's a rogue star. If there is, let's see it.

Wash, rinse, repeat.
You'd have to be patient though, because I believe our next close encounter with another star won't be until around 300,000 - 400,000 years from now?

No, it's not up to me to prove a negative, it's up to you to prove your claim that it did. Show us that the velocity vector is consistent with a sagittarius dwarf star, I'm still waiting. You said you proved it, where is the proof?
Does a low tangential velocity of a nearby star suggest it's likely either coming towards or has already been quite near or in the solar system? (Couldn't it have a low tangential velocity AND a low radial velocity, or if that's an unlikely combo, why so?)
A low tangential and low radial velocity would mean the star's velocity vector is very similar to that of the Sun's. The velocities of local stars in the solar neighborhood are smeared out over several tens of kilometers per second in each dimension (3 dimensions: one towards the Galactic Center "U", towards the direction of Galactic rotation "V", and towards the north Galactic pole "W"). The smaller one draws one box in velocity space (e.g. the velocity of such-and-such star must be within x kilometers/second of such-and-such velocity) the fewer field stars will satisfy that criterion (unless the velocity you originally select is close to that of a nearby stellar cluster or association). So very few stars have velocities within a few km/s of that of the Sun (i.e. ones that would show both tiny tangential motions and radial motions).
Stars with really tiny radial velocities and tiny tangential motions may be scientifically interesting, however, as such velocities are what you'd expect for "solar siblings" (i.e. stars that would have shared the Sun's same birth cluster) - but this is getting off topic. Scholz's star is certainly not such a star, as it is moving ~83 km/s with respect to the Sun.
If a complete ring, the structure does not appear to be completely round. It also appears to be warped, probably from encounters with satellite galaxies orbiting the Milky Way such as the Large and Small Magellanic Clouds and the Sagittarius dwarf galaxy. Its stars are also very dispersed so that observers from a good distance outside the Milky Way would see only a "ghostly" ring because of its low surface brightness (Ibata et al, 2003). Initial observations suggest that stars in the ring are bluer than those found in the galaxy's thick disk (Yanny et al, 2003). Their initial metallicities are low (averaging around 2.5 percent of Sol's abundance of iron, and mostly ranging from 1.3 to 5.0 percent of Sol's) suggest that they are as scarce in elements heavier than hydrogen and helium as many thick disk and halo stars. Some astronomers believe that the ring may be the remains of a satellite galaxy, spun apart by the stronger gravity of the Milky Way. As smaller galaxies are pulled apart, they dissolve into streams of stars and gas around their host galaxies (see the discussion or "star streams" or "tidal trails" from the Sagittarius Dwarf Elliptical Galaxy). Gravity, primarily from unseen dark matter, can hold the ring in a nearly circular orbit around the host galaxy. Previous studies of stellar rings around other galaxies suggest that a substantial portion of galaxies like the Milky Way are formed by a lot of smaller galaxies mixing together, according to SDSS team co-leader Heidi Jo Newberg. If the ring was created by a merger, then it may have occurred billions of years ago, according to SDSS team co-leader Brian Yanny. Alternatively, the stars of the ring could have formed within the Milky Way, according Mike Irwin of the ING team. Its stars could have originally come from the galaxy's spiral disk through warping of the spiral disk from ancient as well as more recent gravitational interactions with satellite galaxies or even larger galactic neighbors. Over time, however, their orbits have been warped or spread over time so that the stars in the ring now wander far from the plane of the spiral disk (Ibata et al, 2003).

It is bordered by Orion to the west, Gemini to the north, Canis Major to the south and Hydra to the east. Other bordering constellations include Canis Minor, Lepus and Puppis.
