NGC 358 is an asterism of four stars in the constellation of Cassiopeia. Two of the members were found to have a similar distance of roughly 1700 light years with Hipparcos data, although the other two did not have well-constrained distances, so its exact nature was uncertain.

Gaia DR3 data shows that the two members TYC 4021-519-1 and TYC 4021-575-1 are not associated due to their very different proper motion and radial velocity. The distance remains remarkable similar for both stars from the Gaia parallax. The other two stars have larger distances.{{Cite journal |last=Gaia Collaboration |date=2022-05-01 |title=VizieR Online Data Catalog: Gaia DR3 Part 1.

The asterism was discovered on February 4, 1865, by the German-Danish astronomer Heinrich Louis d'Arrest.{{cite web |last1=Seligman |first1=Courtney |title=NGC 358 |url=http://cseligman.com/text/atlas/ngc3a.htm#358 |website=Celestial Atlas |access-date=7 December 2018}}
