Supernova impostors are optical transients that, despite being assigned a supernova designation, do not signal the death of a massive star or an accreting white dwarf. Instead, most impostors are likely to be the result of a major eruption from a massive star. Although the physical cause of these eruptions is still debated, tidal interactions from a binary companion has recently gained traction as a possible explanation for observations of some supernova impostors. In this talk, I will discuss the particularly interesting impostor SN 2010da, which is (so far) unique among this class of objects due to its high-luminosity, variable X-ray emission. The X-ray emission is consistent with accretion onto a neutron star, making SN 2010da both a supernova impostor and likely high mass X-ray binary. If it is indeed a high mass X-ray binary, it is extremely young: CMD modeling of the coeval stellar population revealed by HST imaging constrains the age of SN 2010da system to <5 Myr. This age is consistent with the theoretically predicted first onset of X-ray production in X-ray binaries, making SN 2010da an important object for understanding massive binaries and high mass X-ray binary formation.
