The object is relatively far at a distance of 1,050 light years but is approaching the Solar System with a heliocentric radial velocity of . HD 196775 has a high peculiar velocity of compared to neighboring stars, indicating that it may be a runaway star.
HD 196775 has a general stellar classification of B3 V, indicating that it is an ordinary B-type main-sequence star. However, once source gives it a class of B4 Vn, making it slightly cooler and having broad absorption lines due to rapid rotation. It has an angular diameter of, yielding a radius 4.13 times that of the Sun. At present it has 7 times the mass of the Sun and shines at from its photosphere at an effective temperature of, giving it a whitish blue hue. HD 196775 is 36 million years old and is spinning rapidly with a projected rotational velocity of .
