The catalogued J2000 position is carried along the great circle the object's own published motion puts it on, at a constant velocity, and the result is referred to the true equator and equinox of this instant. Those are separate things: the motion moves the object, and the rotation turns the grid under it by about fifty arcseconds a year, with nutation adding up to another seventeen.","excluded":"Parallax, the radial-velocity perspective term, aberration and refraction; each is below the accuracy of the catalogued positions themselves. An object with no published proper motion comes back where the catalogue has it rather than at a fabricated zero, and says so with a null pm_ra_mas_yr. A body with no fixed position is not propagated at all — its place comes from an ephemeris, which is what /api/v1/visible answers with."},"slug":"hip-94235-b","name":"HIP 94235 b","class":"neptune_like_planet","category":"exoplanet","object_type":"Neptune-like planet","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":190.84909979544156,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":287.7411441,"dec_deg":-60.2726358,"epoch_ra_deg":288.335445,"epoch_dec_deg":-60.228504,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"HIP 94235","semi_major_axis_km":11773352.42409,"periapsis_km":null,"mass_kg":2.2634516218929326e+27,"mass_msun":0.00113832,"constellation":"Pavo","discovered":"2022","featured":false,"url":"https://spacecatalog.org/object/hip-94235-b","radius_km":19134.300000000003,"radius_kind":null,"data_quality":"The published mass and radius imply a density no material has.
