Su posición moderadamente boreal significa que esta estrella es observable especialmente desde el hemisferio norte, donde se muestra en lo alto del cielo en el cinturón templado; desde el hemisferio sur su observación es más penalizada, especialmente fuera de su cinturón tropical. Siendo de magnitud 3.80, se puede observar incluso desde pequeños centros urbanos sin dificultad, aunque un cielo no excesivamente contaminado es más indicado para su detección.La estrella es una subgigante azul de tipo espectral B3IV, clasificada como una variable de pulsación lenta, similar a las variables Beta Cephei; su brillo varía en 0,02 magnitudes durante 3,49 días. IOTA Herculis es también un binario espectroscópico con un período orbital de 113,8 días, teniendo un compañero que está a aproximadamente 1 UA de distancia del principal. Parece tener otro compañero, una distancia de 30 UA, con un período orbital de aproximadamente 60 años, y un componente adicional, que parece estar también relacionado con el sistema, está visualmente a 2'' de distancia, que corresponden a una distancia de al menos 18. UA 000.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
