This globular cluster was discovered by William Herschel on September 20, 1786 and cataloged as H III.558.
NGC 7492 is one of the outlying globular clusters of our Milky Way galaxy, at
its distance of about 84,000 light-years from us, and 81,200 light-years from
the Galactic Center. As its concentration class XII indicates, it is one of the
loosest and least compressed globular clusters, and lacks a dense central core.
Its diameter is
Because of its large distance, it is difficult to be resolved into stars:
The brightest stars are of visual mag 15.5, the horizontal branch giants of
mag 17.6. While far out at these times, globular cluster NGC 7492 is rapidly
approaching us, at about 208 km/s.
