Top 10 Nearest Stars to the Earth

[Estimated read time: 3 minutes]

A star can be defined as a big ball composed of hydrogen and helium gas that shines extremely bright. The core of star is dense and hot. Do you know there are 56 stellar systems including solar system. And these systems contain a total 56 hydrogen-fusing stars. Some time we have anxiety to know the closet of all these twinkling stars. Here is the list of the Top 10 Nearest Stars to the Earth, according to the distance between stars and Earth in Light Year.

10. Ross 248 – 10.3 LY

Ross 248 was first discovered by Frank Elmore Ross in 1926. It is too dim to be seen with the naked eyes. This star has about 12% of the sun’s mass and 16% of the sun’s radius. It is estimated that the trajectory of the Ross 248 will bring it near to the solar system in the future.

9. Ross 154 – 9.6 LY

Ross 154 was first categorized by American astronomer, Frank Elmore Ross in 1925. The distance to this star from earth is estimated from parallax measurements. It is the nearest star in the southern constellation Sagittarius. It has an estimated 17% of the sun’s mass and 24% of the sun’s radius.

8. Luyten 726-8 – 8.7 LY

Luyten 726-8 has two stars and first discovered in 1948 by Willem Jacob Luyten. Both the stars are of equal brightness. It is categorized in red dwarf stars and flare star which means it can go under the dramatic increase in brightness for a few minutes.

7. Sirius – 8.5 LY

Sirius also has two stars and popularly known as the Dog Star. It is the brightest star in the sky, about twice massive and 25 times more luminous than the Sun. It is the closest star after the Sun which can be seen with the naked eyes. According to the scientists, it will continue to be the brightest star in the sky for the next 210,000 years.

6. Lalande 21185 – 8.2 LY

Lalande 21185 is located in the constellation of Ursa Major. It is too dim to see with the naked eyes and is visible through a small telescope. It was discovered in 1801 by French astronomer Jerome Lalande. It is also classified as a flare star that emits X rays.

5. Wolf 359 – 7.7 LY

Wolf 359 is located in the constellation Leo and can only be seen through a large telescope. It was first cataloged in 1917 by German astronomer, Max Wolf. It is a flare star and emits strong bursts of X ray and gamma ray radiation that have been observed by space telescope.

4. Luhman 16 – 6.6 LY

Luhman 16 is a binary star system located in the southern constellation Vela. These stars were discovered by Kevin Luhman of Pennsylvania State University and a researcher from the Penn state’s center. It is one of the low dense stars and has around 5% of Solar System’s mass.

3. Barnard’s Star – 5.9 LY

Barnard’s Star is a very low mass star located in the constellation of Ophiuchus. It is named for American astronomer EE Barnard but he was not the first to observe the star. Barnard’s Star is 12 billion years old (which is older than the Sun), making it the oldest star in the Milky Way galaxy.

2. Alpha Centauri – 4.3 LY

Alpha Centauri is the brightest star in the southern constellation of Centaurus and the third brightest star in the sky. The Alpha Centauri is 6 billion years old. It has 1.1 times the mass of the Sun’s mass and radius 1.2 times of the Sun’s radius.

1. Sun – 0.0000158 LY

The Sun is the closest star to earth and located in the center of the solar system. It has eight planets revolving around it and contains around 99.86% of the solar system’s mass. It formed about 4.6 billion years ago due to the gravitation collapse in a large molecular cloud. It fuses about 620 million metric tons of hydrogen each second. The diameter is around 109 times of earth and its mass is 330,000 times the mass of Earth.
