	Gliese 710
		Many astronomers now refer to this star as Gliese 710 by its designation in the famous Gliese Catalogue of Nearby Stars (CNS, now ARICNS database) of Wilhelm Gliese (1915-93), who was a longtime astronomer at the Astronomiches Rechen-Institut at Heidelberg (even when it was at Berlin).
		Gliese 710 is a relatively dim, main sequence orange-red or red dwarf star of spectral and luminosity K5-M1 V (ARICNS; Joy and Abt, 1974; and Upgren et al, 1972).
		Gliese 710 B? According to García-Sánchez et al (1999), astrometric residuals in early proper-motion measurements suggested a possible periodicity of 4.7 years (around 1,700 days) but its significance was uncertain (Grossenbacher et al, 1968; and V.

		Gliese 710 ist ein Roter Zwergstern, der etwa 40-60% der Sonnenmasse besitzt.
		Gliese 710 ist also ein unauffälliger Stern, würde er nicht mit einer Geschwindigkeit von 14km /Sekunde auf die Sonne zurasen.
		Ein Zusammenstoss zwischen Sonne und Gliese 710, oder andere merkliche Beeinflussungen der beiden Sterne, sind aus heutiger Sicht nicht zu erwarten.

	Gliese 710 (Site not responding. Last check: 2007-11-02)
		Gliese 710 is a red dwarf star in the constellation Serpens Cauda, with visual magnitude 9.66 and a mass of 0.4–0.6 solar masses.
		In a time interval of ±10 million years from the present, Gliese 710 is the star whose combination of mass and close approach distance will cause the greatest gravitational perturbation of our solar system.
		Interestingly, the star with the second greatest perturbational effect in the past or future 10 million years was Algol, a triple star system that passed no closer than 9.8 light years, 7.3 million years ago, but with a considerably larger total mass of 5.8 solar masses.

		This future stellar encounter was discovered by researchers Joan Garcia-Sanchez and Robert Preston (JPL), and collaborators while studying stars in the solar neighborhood using data from the Hipparcos Astrometry Satellite.

		Gliese 710 is a dull, red dwarf: a small, dim star.
		And that's not the kind of object you want to find in your backyard in the morning: Gliese 710 is more than fifty times as big as the Earth, and more than 100,000 times as massive.

		Garcia-Sanchez has found evidence that Gliese 710 is today moving more slowly towards the Sun than it was several decades ago.
		If so, the closest distance to which Gliese 710 will approach may be nearer or farther than in the team's initial estimate.

		But even if Gliese 710 misses us, it’s fairly likely that some other star out there is headed our way.
		Even a near miss of the Oort cloud by a passing star might be enough of a gravitational tug to redirect some comets toward the inner solar system; Gliese 710, by current estimates, will pass right through this cloud.
		Gliese 710, by contrast, will streak by quickly, thus disturbing fewer comets.

		Gliese 710 isn’t on an exact collision course, but it will pass very close.
		So, as Gliese 710 passes by, it will be nearly as close to these Oort cloud objects as is our own Sun.
		Gliese 710 has less mass, but it still has a LOT of mass (half the Sun’s mass) with which to disturb orbits.

		The star with the greatest possibility of perturbing the Oort cloud in the next 10 million years is Gliese 710.
		So far, only one potential Oort cloud object has been discovered; (90377) Sedna.

		However, the very existence of this pattern is not widely accepted, and the existence of the Nemesis star is highly controversial.

		From the article: “For the future passage of Gl 710, the star with the closest approach in our sample, we predict that about 2.4 × 106 new comets will be thrown into Earth-crossing orbits, arriving over a period of about 2 × 106 yr.
		Granted we do not know that it has one, but if such debris collections are normal to star formation, one would think the solar system could pass right through that one.

		In the far distant future--more precisely 1.4 million years from now--the nearby red dwarf star Gliese 710 will pass through the swarm of comets in the Oort cloud.
		While Gliese 710 will not come close enough to directly affect the Earth, it will likely knock some comets out of their orbits and possibly send a few down toward the sun.
		Whenever comets enter the solar system there is the risk that one or more may strike the Earth.

		From the Hipparcos data, it will pass within about one light-year, one million years from now.
		That may mean it is orbiting around another star, so far unidentified.

		However scientists have recently found evidence of "rebel" stars that seem to be moving either out from the galactic center or in toward it.
		Our next encounter with such a star will occur in about 1.4 million years from now when Gliese 710 will pass within a light year of us.
		To sum it all up, we are always moving, but the distances in space are so vast things only go by us rarely and when they do they are still very far away.

		The closest encounter with another star won’t occur for another 1.4 million years, when Gliese 710 will pass within 1 light year of the Sun (some 70,000 AU, perhaps within the Oort Cloud of cometary debris).
		In any case, Gliese 710 does not appear to be one of the stars affected by galactic density waves; its motion around the galactic center seems relatively normal.

		(1999) look at the paths of nearby stars and project that in 1.5 million years the star Gliese 710 (a dwarf star of.6 solar masses) will pass within 1 light year of Earth and actually enter the Oort cloud.
		The probable reason the authors do not address this the impossibility of predicting specifically which comets will be ejected from the Oort cloud and sent towards Earth, and which of those will actually collide with the planet.
		The article looked 10 million years backward and 10 million years forward, and Gliese 710 is the best candidate they found for an Oort cloud perturber.
