We use a combination of Hipparcos space mission data with the USNO dedicatedground-based astrometric program URAT-Bright designed to complement and verifyGaia results for the brightest stars in the south to estimate the smallperturbations of observed proper motions caused by exoplanets. One of the 1423bright stars in the program, $\delta$ Pav, stands out with a small propermotion difference between our long-term estimate and Gaia EDR3 value, whichcorresponds to a projected velocity of $(-17,+13)$ m s$^{-1}$. This differenceis significant at a 0.994 confidence in the RA component, owing to theproximity of the star and the impressive precision of proper motions. Theeffect is confirmed by a comparison of long-term EDR3-Hipparcos and short-termGaia EDR3 proper motions at a smaller velocity, but with formally absoluteconfidence. We surmise that the close Solar analog $\delta$ Pav harbors along-period exoplanet similar to Jupiter.
