... We detect three main diffuse components: the Virgo ICM at 2.4 keV, the extended halo of M86 at 1.2 keV, and the cooler central and stripped gas of M86 at 0.8 keV. ... The data are inconsistent with a radial orbit, and imply inner and outer turning radii of ri 300 kpc and ro 8.8 Mpc, indicating that M86 is, at best, only weakly bound to the Virgo cluster. ... Constraints on the Orbit of M86 5 Knowing the orbit of M86 is the key to understanding its interaction with the Virgo cluster. ...
