The '''International Near-Earth Asteroid Survey''' ('''INAS''') was an [[astronomical survey]], organized and co-ordinated by prolific American astronomer [[Eleanor Helin]] during the 1980s. It is considered to be the international extension of the [[Planet-Crossing Asteroid Survey]] (PCAS). While PCAS operated exclusively from the U.S. [[Palomar Observatory]] in California, INAS attempted to encourage and stimulate worldwide interest in [[asteroid]]s, and to expand the sky coverage and the discovery and recovery of [[near-Earth objects]] around the world.<ref name="WITI" /><ref name="Helin-2000" />

The [[International Astronomical Union|IAU]]'s [[Minor Planet Center]] credits INAS with the discovery of 8 minor planets in 1986 (compared to 20 discoveries made by PCAS during 1993–1994).<ref name="MPC-Discoverers" /> One of the discoveries was the 7-kilometer sized main-belt asteroid [[4121 Carlin]].<ref name="MPC-Carlin" />
