Luhman 16 A and Luhman 16 B are the closest brown dwarf stars to Earth, and the third-nearest star system to the Solar System. [e] SSSPM J0829-1309: 61,300 Red dwarf: An L2 dwarf that is fusing hydrogen. Similarly to 2MASS J0523-1403, SSSPM J0829-1309 is one of the least luminous and massive hydrogen-fusing stars, and is smaller than Jupiter ...
The smaller star, OGLE-TR-122B, is estimated to have a radius around 0.12 solar radii, or around 20% larger than Jupiter's, and a mass of around 0.1 solar masses, or approximately 100 times Jupiter's. This makes its average density approximately 50 times the Sun's [2] [3] or over 80 times the density of water.
EBLM J0555-57 is a triple star system approximately 670 light-years from Earth. The system's discovery was released on July 12, 2017. EBLM J0555-57Ab, the smallest star in the system, orbits its primary star with a period of 7.8 days, and currently is the smallest known star with a mass sufficient to enable the fusion of hydrogen in its core.
The star has a mass of 0.80 M ☉ and a radius of 0.79 R ☉. It has a temperature of, 5417 K and is 5.66 billion years old. In comparison, the Sun is 4.6 billion years old, [8] and has a temperature of 5778 K. [9] The star's apparent magnitude, or how bright it appears from Earth's perspective, is 9.71. Therefore, it is too dim to be seen with ...
V723 Monocerotis is a variable star in the constellation Monoceros. It was proposed in 2021 to be a binary system including a lower mass gap black hole candidate nicknamed "The Unicorn". [1] Located 1,500 light years from Earth, it would be the closest black hole to our planet, and among the smallest ever found. [8] [9]
Astronomers used NASA's James Webb Space Telescope to reveal 44 stars in a galaxy so far away, its light dates to when the universe was half its age. In 'groundbreaking' study, astronomers detect ...
A star is a massive luminous spheroid astronomical object made of plasma that is held together by its own gravity.Stars exhibit great diversity in their properties (such as mass, volume, velocity, stage in stellar evolution, and distance from Earth) and some of the outliers are so disproportionate in comparison with the general population that they are considered extreme.
The most powerful telescope to be launched into space has made history by detecting a record number of new stars in a distant galaxy. NASA's James Webb Space Telescope, history's largest and most ...
