Encyclopedia
p Velorum is a triple star system in the constellation
Vela
. It is approximately 86.5 light years
from Earth
.
The primary component, p Velorum A, is a yellow-white F-type
subgiant with an apparent magnitude
of +4.5. It is a spectroscopic binary whose components have an orbital period of 10.21 days. The companion star, p Velorum B, is a white A-type
main sequence dwarf
with an apparent magnitude of +5.1. It is located 0.3 arcseconds from the primary and has an orbital period of 16.3 years. The system has a combined apparent magnitude of +3.84.
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....

Stellar classification
In astronomy, stellar classification is a classification of stars based on their spectral characteristics. The spectral class of a star is a designated class of a star describing the ionization of its chromosphere, what atomic excitations are most prominent in the light, giving an objective measure...

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 HertzsprungāRussell diagrams after their co-developers, Ejnar Hertzsprung and Henry Norris Russell...
