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.

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.

The easiest way to determine stellar distance to the Sun for objects at these distances is , which measures how much stars appear to move against background objects over the course of Earth's orbit around the Sun. As a(parallax-second) is.

Our closest neighboring stars are all part of the same solar system: Alpha Centauri. This triple star system – consisting of Proxima Centauri, Alpha Centauri A, and Alpha Centauri B – attracts a lot of interest because it hosts planets, including one that may be similar to Earth.
A team of astronomers using the European Southern Observatory''s Very Large Telescope (ESO''s VLT) in Chile 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 discovered orbiting this star. At just a quarter of Earth''s mass, the planet is also
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
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 of these stars, Proxima Centauri, is just about 4.24 light
Proxima Centauri lies about 2.2 trillion kilometers away from the main pair of stars in this system. It''s an M-type red dwarf star, and much, much dimmer than the Sun. Astronomers have found a planet orbiting this star, making it the nearest planet to our own solar system ''s called Proxima Centauri b and it''s a rocky world, just as Earth is.
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 Sun''s closest stellar neighbor is located in the Centaurus constellation, roughly 38 trillion kilometers away. Proxima Centauri is a small red dwarf star that was discovered in 1915.
For example, the nearest star system to ours is the triple star system of Alpha Centauri, at about 4.3 light years away. That''s a more manageable number than 25 trillion miles, 40 trillion kilometers or 272,000 AU. Light years also provide some helpful perspective on solar system distances: the Sun is about 8 light minutes from Earth.
Formerly, before this announcement, astronomers believed that Alpha Centauri was the closest star to our solar system. However, Proxima – a relatively small red dwarf star – is closer at a
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
It is the faintest of the three stars in the Alpha Centauri system, the nearest star system to Earth. Located at a distance of only 4.244 light years from Earth, Proxima is the nearest star to the Sun. With an apparent
Obviously, the top titleholder on this list is the central star of our solar system: the Sun. Yes, it''s a star and a very nice one at that. Astronomers call it a yellow dwarf star, and it has been around for about five billion years.
We know there are planets orbiting other stars near our Solar System, and many of these stars are similar to our own. Over 2000 exoplanets have been identified, many of which are believed to be
The nearest stars. Two-thirds of our stellar neighbors are cool M-class dwarf stars. not counting the eight officially logged in our solar system. The only other star in our collection with

The Sun, the Alpha Centauri system, and other nearby stars all move around the Milky Way over time, and they approach and pass each other as they travel. In another 10,000 years or so, the closest star will be something else. Indeed, studies of stars'' motions show that many other stars may have ventured close to the solar system throughout its
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
Proxima Centauri is the closest star to the Sun, about 4.2 light-years away in the Alpha Centauri system. As a red dwarf star—the most common type of star—Proxima Centauri is about seven times smaller than the Sun and a little more than half as hot, at 3,100 kelvins. In fact, the tiny star is only 50 percent larger than the planet Jupiter.
Alpha Centauri, triple star system, the faintest component of which, Proxima Centauri, is the closest star to the Sun, about 4.2 light-years distant. The two brighter components, called A and B, about 0.2 light-year
By cosmic standards, Proxima Centauri is right next door. At 4.2 light-years away, it is the closest star to our sun, which makes the planets around Proxima the closest planets to us of any in the
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
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
Shining brightly in this Hubble image is our closest stellar neighbor: Proxima Centauri. Proxima Centauri lies in the constellation of Centaurus (The Centaur), just over four light-years from Earth. 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 []
Proxima Centauri is the closest star to the Sun, about 4.2 light-years away in the Alpha Centauri system. As a red dwarf star—the most common type of star—Proxima Centauri is about seven
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.
