NGC 602 is a young star cluster 200,000 light years away near the Small Magellanic Cloud. It is surrounded by the Nebula N90.
Ionization is from a number of large young blue stars including Sk 183, an extremely hot O3 main sequence star.
There is what appears to be a faint Planetary Nebula which may be SMC-B Bru 2-165
