Over long periods of time, the slow independent motion of stars change in both relative position and in their distance from the observer. This can cause other currently distant stars to fall within a stated range, which may be readily calculated and predicted using.

Until now, the top candidate for the closest flyby of a star to the solar system was the so-called "rogue star" HIP 85605, which was predicted to come close to our solar system in 240,000 to 470,000 years from now. However, Mamajek and his collaborators have also demonstrated that the original distance to HIP 85605 was likely underestimated
The image on the preceding page was created to demonstrate that Alpha Centauri is not a star, but really a star system. Of the three stars in the system, the dimmest - called Proxima Centauri - is actually the nearest star to the Sun. The two bright stars, called Alpha Centauri A and B form a close binary system; they are separated by only 23
At 4.3 light-years away, Alpha Centauri A and B are the nearest Sun-like stars to our solar system. They orbit with Proxima Centauri as a triple star system.Alpha Centauri A is a Class G star that is 1.1 times the mass of
At 4.3 light-years away, Alpha Centauri A and B are the nearest Sun-like stars to our solar system. They orbit with Proxima Centauri as a triple star system.Alpha Centauri A is a Class G star that is 1.1 times the mass of the Sun. Alpha Centauri B is slightly cooler Class K star that is 0.9 times the mass of the Sun. Proxima Centauri, the closest star to the Sun, is a much
The Alpha Centauri system is 4.35 light-years away from our beloved planet Earth, and it is actually a triple-star system, making it a cosmic rarity being a part of only 10% of systems that share the same trait (via the Daily Beast).The first two stars in the system — Alpha Centauri A and Alpha Centauri B (both pictured) — are approximately 23 astronomical units
A team of scientists have calculated how long it would take four operating spacecraft to reach the nearest star. our solar system and are now the star system HIP 117795 in the Cassiopeia
Alpha Centauri consists of three known stars (including Proxima). Of the three, Proxima is closest, at 4.2 light-years away. Alpha Centauri appears as the 3rd-brightest star in Earth''s sky. But Proxima is too faint to see with the eye. It''s a small, dim, low-mass star, with its own planetary system.
Astronomers have found evidence of another planet orbiting Proxima Centauri, the closest star to our Solar System. This candidate planet is the third detected in the system and the lightest yet
Alpha Centauri is a star system with components 4.2 to 4.4 light-years from Earth and comprises three stars. It is the closest star system to the solar system, and one of its stars...
In fact, at 4.25 light-years away, Proxima is the closest-known star to our solar system. Help! EarthSky needs your support to continue. Our yearly crowd-funding campaign is going on now. Donate here.

Alpha Centauri (α Centauri, α Cen, or Alpha Cen) is a triple star system in the southern constellation of Centaurus. It consists of three stars: Rigil Kentaurus (α Centauri A), Toliman (α Centauri B), and Proxima Centauri (α Centauri C). Proxima Centauri is the closest star to the Sun at 4.2465 light-years (1.3020 pc). α Centauri A and B are Sun-like stars (class G and K, respectively) that togethe
Proxima Centauri is the nearest star to Earth after the Sun, located 4.25 light-years away in the southern constellation of Centaurus. This object was discovered in 1915 by Robert Innes. It is a small, low-mass star, too faint to be
This is important for the viability of life in the nearest star system outside the Solar System. Chandra data from May 2nd, 2017 are seen in the pull-out, which is shown in context of a visible-light image taken from the ground of the Alpha Centauri system and its surroundings. Alpha Centauri is a triple star system located just over four
The closest system is Alpha Centauri, with Proxima Centauri as the closest star in that system, at 4.2465 light-years from Earth. The brightest, most massive and most luminous object among those 131 is Sirius A, which is also the brightest star in Earth''s night sky; its white dwarf companion Sirius B is the hottest object among them.
Although it looks bright through the eye of Hubble, as you might expect from the nearest star to the Solar System, Proxima Centauri is not visible to the naked eye. Its average luminosity is very low, and it is quite small compared to other stars, at only about an eighth of the mass of the Sun. However, on occasion, its brightness increases.
Proxima Centauri b (or Proxima b), [5] also referred to as Alpha Centauri Cb, is an exoplanet orbiting within the habitable zone of the red dwarf star Proxima Centauri, which is the closest star to the Sun and part of the larger triple star system Alpha Centauri is about 4.2 light-years (1.3 parsecs) from Earth in the constellation Centaurus, making it and Proxima d, along with the

Alpha Centauri (α Cen) is a triple star system located in the constellation Centaurus is the nearest star system to the Sun and the third brightest point of light in the sky outside the solar system, after Sirius and Canopus outshines the northern luminaries Arcturus, Vega and Capella.With a combined apparent magnitude of -0.27, Alpha Centauri is also the
Mamajek thinks that Scholz''s star, now known as the star that came closest to our solar system, could eventually lose that title. Extremely precise data from the European Space Agency''s new Gaia space probe will likely reveal more near misses, possibly closer ones. And in any case, another close pass by a star known as GJ 710 is due in
The nearest stars to Earth are three stars that lie about 4.37 light-years away in the Alpha Centauri triple-star system. The closest stars, typically have about 0.9 to 1.1 solar masses with
What Is The Closest Star? The Milky Way Galaxy is home to more than 100-billion stars that span a distance of over 100,000 light years.Thus, most of the stars in our galaxy are very far away from our solar system, yet some are practically in our cosmic backyard.The closest star to our solar system is Proxima Centauri, located a mere 4.2 light years away.
