HD 35519 is a K-type giant star in the direction of open cluster Messier 38. It was once treated as a cluster member,[12] but is now known to be a foreground object located at a distance of about 699 light-years (214 pc).[2]
The star has expanded to about 30 times the Sun's radius and radiates around 259 times the Sun's luminosity at a temperature of about 4,265 K.[7][8] HD 35519 is 5.6 billion years old and has 2.7 times the Sun's mass.[9][6] At an apparent visual magnitude of 6.3062[3], the star is visible to the naked eye under good viewing conditions.
