Encyclopedia
Gliese 179 is a 12th magnitude
M-type main sequence
star
located approximately 40 light years away in the constellation
Orion
. This star is smaller, cooler, fainter, and less massive than our Sun. Also its metal
content is twice as much as the Sun. In 2009, a gas giant
planet was 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...
