As with many other stars of its kind, V1429 Aquilae is sufficiently remote that its distance must be determined by indirect methods: estimations range between 3 and 4.3 kiloparsecs (9,800-14,000 light years), with the most likely value nearer to the former, lower figure. If that is the case, then its total luminosity has been estimated to be more than 1,200,000 times that of the Sun, having a radius 60 times larguer than that of our star, and being 80 times more massive than the Sun. This places it among the most luminous stars of the Milky Way. However, despite its high luminosity, it's so heavily reddened by the interstellar dust that it's totally unobservable with the naked eye and needs a telescope for its observation.
V1429 Aquilae is not only a Be star but also a Luminous Blue Variable candidate due to its high luminosity and later studies have shown it's actually a binary system surrounded by a disk of gas as well as a very extensive bipolar nebula.
