Top panel: trajectory on the sky of NGC 2419’s possible orbits (within 1σ), where that obtained by starting from its current position and velocity (indicated by a triangle) is shown with the black dashed line. The colour-coding represents the (heliocentric) distance. For comparison, we also show the current position and orbit of the Sagittarius dwarf spheroidal galaxy (diamond and magenta dot-dashed line), integrated in the same Galactic potential, and the positions of globular clusters (coloured circles) possibly associated to Sagittarius according to Law & Majewski (2010b). Bottom panel: as the top panel, but where the colour-coding represents the (heliocentric) radial velocity.
