Encyclopedia
BD-08°2823 is a 9.86 magnitude
K-type main sequence
star
located approximately 137 light years away in the constellation
Sextans
. This star is smaller, cooler, fainter, and less massive than our Sun. Also its metal
content is six-sevenths as much as the Sun. In 2009, two gas giant
planets were found in orbit around the star.
Apparent magnitude
The apparent magnitude of a celestial body is a measure of its brightness as seen by an observer on Earth, adjusted to the value it would have in the absence of the atmosphere...

Main sequence
The main sequence is a continuous and distinctive band of stars that appears on plots of stellar color versus brightness. These color-magnitude plots are known as Hertzsprung–Russell diagrams after their co-developers, Ejnar Hertzsprung and Henry Norris Russell...

Star
A star is a massive, luminous sphere of plasma held together by gravity. At the end of its lifetime, a star can also contain a proportion of degenerate matter. The nearest star to Earth is the Sun, which is the source of most of the energy on Earth...
