Toomre diagram showing all exoplanet-host stars in The Extrasolar Planets Encyclopaedia for which it was possible to derive Galactic space velocities (U_LSR, V_LSR, W_LSR) relative to the local standard of rest (LSR). Kepler-444 is denoted by a blue star. HIP 13044 and Kapteyn's star fall outside the plotted range. Dashed lines represent curves of constant peculiar velocity, viz., and 100 km s⁻¹.
