Using three-dimensional, moving-mesh simulations, we investigate the futureevolution of the recently discovered gas cloud G2 traveling through thegalactic center. From our simulations we expect an average feeding rate ontoSgr A* in the range of $(5-19) \times 10^{-8} M_\odot\mathrm{~yr}^{-1}$beginning in 2014. This accretion varies by less than a factor of three ontimescales of about 1 month, and shows no more than a factor of 10 differencebetween the maximum and minimum observed rates within any given model. Theserates are comparable to the current estimated accretion rate in the immediatevicinity of Sgr A*, although they represent only a small (<10%) increase overthe current expected feeding rate at the effective inner boundary of oursimulations $(r_\mathrm{acc} = 750 R_S \sim 10^{15} \mathrm{cm})$. We alsoexplore multiple possible equations of state to describe the gas. In examiningthe Br-$\gamma$ light curves produced from our simulations, we find that all ofour isothermal models predict significant (factor of 10) enhancements in theluminosity of G2 as it approaches pericenter, in conflict with observations.Models that instead allow the cloud to heat as it is compressed do better atmatching observations.
