data
56 Orionis is a single,[10] variable star in the equatorial constellation of Orion. It has an orange hue and is faintly visible to the naked eye with an apparent visual magnitude that fluctuates around 4.76.[2] The star is located at a distance of approximately 1,130[1] light years from the Sun based on parallax.[1] It is drifting further away with a radial velocity of +11 km/s.[1] The star has a peculiar velocity of 19.0+2.9 −3.1 km/s relative to its neighbors, and may be a runaway star.[6]
This object is a bright giant star with a stellar classification of K2-IIb.[4] It is a suspected variable star of unknown type with a brightness that has been measured varying from 4.73 down to 4.78.[3] The star is about 61[6] million years old with 6.4[6] times the mass of the Sun and is spinning with a projected rotational velocity of 3.5.[8] Having exhausted the supply of hydrogen at its core, the star has expanded to 92[1] times the radius of the Sun. It is radiating 2,547 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,270 K.[1]
It has one reported visual companion, designated component B, with magnitude 13.5 and angular separation 42.9″.[11]
