HD 85390
Encyclopedia
HD 85390 is a main sequence
star
of spectral class K1 located approximately 111 light years away in the constellation
Vela
, appearing as 8.55 magnitude
star. This star is smaller, cooler, dimmer, and less massive than our Sun. Also its metal
content is seven-sixths as much as the Sun. In 2009, a planet with a minimum mass of about 1/7 of Jupiter's was found in orbit around the star.
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 HertzsprungāRussell 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...

Constellation
In modern astronomy, a constellation is an internationally defined area of the celestial sphere. These areas are grouped around asterisms, patterns formed by prominent stars within apparent proximity to one another on Earth's night sky....
Vela

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...
