摘要：

We have measured the distance to the Local Group dwarf irregular galaxy IC 10 from near-infrared JHK observations of Cepheids. The reddening-corrected distance modulus is 24.57+/-0.21 mag or 0.82+/-0.08 Mpc. This distance lies at the short end of the range of previous estimates, and is significantly more accurate than all prior determinations. At this distance, IC 10 is comparable in total mass to the Small Magellanic Cloud, but has much more vigorous star formation. (C) 1996 American Astronomical Society.
