Top 10 Nearest Star System to the Solar System

The Universe comprises of everything that exists from the galactic super clusters to the tiniest sub-atomic particles and has a radius of about 46 billion light years with age about 13 to 15 billion years. The techniques used for measuring the age of the universe are cosmic microwaves background radiations and radio-active dating.

A Star is a type of celestial body or astronomical object consisting of a luminous spheroid of plasma held together by its own gravity. The life cycle of a star starts Stellar Nebula then progressively passes through the phases of proto-star, star, red giant/super giant, planetary nebula/supernova, white dwarf/neutron star and blackhole.

Top 10 nearest Star System to the Solar System

According to the Astronomy, there are 52 stellar systems beyond our own Solar system that currently lie within 16.3 light-years (5.0 parsecs/ parallax-second) of the Sun. These systems contain a total of 63 stars, of which 50 are red dwarfs, by far the most common type of star in the Milky Way. The lists of top 10 nearest Star System to the Solar System are given below:

10. 61 Cygis

It is a binary star system (star system consisting of two stars orbiting around their common barycentre) in the constellation Cygnus, consisting of a pair of K-type dwarf stars.

9. Gx2 GQ Andromedae

It is also known as Groombridge 34 and is a binary star system (star system consisting of two stars orbiting around their common barycentre) in the northern constellation of Andromeda.

8. Ross 248 (Andromedae)

It is also called HH Andromedae or Gliese 905 and, is a small star located in the northern constellation of Andromeda. It was first catalogued by Frank Elmore Ross in 1926.

7. Sirius A & B

It is a star system and the brightest star in the Earth's night sky. It is also known Alpha Canis Majoris or the Dog Star.

6. UV Ceti A & B

It is also known as Luten 726-9 or Gliese 65. It is binary star system (star system consisting of two stars orbiting around their common barycentre) which was discovered in 1948 by Willem Jacob Luyten.

5.  Lalande 21185

It is a star in the constellation of Ursa Major.

4. Wolf 359 (CN Leows)

It is a red dwarf star located in the constellation Leo, near the ecliptic. It is one of the known faintest and lowest-mass stars.

3. Barnard’s Star

It is a very-low-mass red dwarf about 6 light-years away from Earth in the constellation of Ophiuchus. It is named after the American astronomer E. E. Barnard.

2. Alpha Centauri A & B

It is second closest to the Solar System, being 4.34 light-years (1.34 pc) from the Sun. It consists of three stars: Alpha Centauri A (also named Rigil Kentaurus) and Alpha Centauri B (also named Toliman), which form the binary star Alpha Centauri AB, and a small and faint red dwarf, Alpha Centauri C (also named Proxima Centauri).

1. Proxima Centauri

It is a red dwarf, a small low-mass star, about 4.244 light-years (1.301 pc) from the Sun in the constellation of Centaurus. It was discovered in 1915 by Robert Innes.

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