Veritate ( Flamsteed designation : 14 Andromedae , abbreviated 14 And ) is a red giant in the constellation Andromeda , the approximately 249 light years from the sun away. It is a 5th magnitude star and can therefore be seen with the naked eye in a moonless night sky and without light pollution . Veritate has a planetary system with at least one known exoplanet .
Origin of name
The star, inconspicuous to the naked eye, was mainly known under its Flamsteed name until 2015 and had no historical proper name. After a public competition by the International Astronomical Union (IAU) to name exoplanets and their central stars, 14 Andromedae received the official name Veritate on December 15, 2015 , derived from the Latin word "Veritas" for "truth". The name originally proposed by the Thunder Bay Center of the Royal Astronomical Society of Canada was Veritas , but it was changed because of the similarity to the asteroid (490) Veritas .
properties
Veritate is a red giant of the spectral class K with more than twice the solar mass and about eleven times the solar radius . It may also be a variable star . In the past it was classified as a main sequence star of the spectral class A or F in an early stage of development.
Planetary system
→ Main article: Spe (exoplanet)
In 2008, a planet orbiting the star with approximately five times the minimum mass of Jupiter was detected using the radial velocity method . This was given the official name Spe by the IAU in 2015 .
