| dbo:abstract | HD 56405 is a star in the southern constellation of Canis Major. It is white in hue and is dimly visible to the naked eye with an apparent visual magnitude of 5.45. To the east of HD 56405 is the open cluster NGC 2360, also known as Caroline's Cluster. The distance to HD 56405, as determined from parallax measurements, is approximately 249 light years. It is drifting further away with a radial velocity (RV) of about +6 km/s. Although classed as a single star, it is to suspected to vary in RV. This is an A-type main-sequence star with a stellar classification of A1V. It was classed as a candidate Lambda Boötis star, but as of 2015 this classification has been rejected by astronomers due to the star having an inconsistent UV flux, possible RV variability, and a fairly high rotation rate. The star is about 212 million years old with 2.13 times the mass of the Sun and is spinning with a projected rotational velocity of 149 km/s. It is radiating 39 times the luminosity of the Sun from its photosphere at an effective temperature of around 9,562 K.

(it) HD 56405 är en ensam stjärna belägen i den norra delen av stjärnbilden Stora hunden. Den har en skenbar magnitud av ca 5,45 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallax enligt Gaia Data Release 2 på ca 13,1 mas, beräknas den befinna sig på ett avstånd på ca 249 ljusår (ca 76 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 6 km/s. Öster om stjärnan ligger den öppna stjärnhopen , även känd som Carolines stjärnhop.
