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":"hd-56414-b","name":"HD 56414 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":887.8531067291874,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":107.8436846,"dec_deg":-68.8333403,"epoch_ra_deg":107.817941,"epoch_dec_deg":-68.876947,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"HD 56414","semi_major_axis_km":34257912.3903,"periapsis_km":null,"mass_kg":7.942983264162534e+25,"mass_msun":0.0000399464,"constellation":"Volans","discovered":"2022","featured":false,"url":"https://spacecatalog.org/object/hd-56414-b","radius_km":23662.751,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"HD 56414","host_v_mag":9.217,"uncertainties":{"radius_km":[1275.6200000000001,1275.6200000000001],"distance_ly":[7.087378087784835,7.1982712562085265],"host_mass_solar":[0.11,0.11],"inclination_deg":[0.4,0.4],"host_radius_solar":[0.065,0.065],"host_temperature_k":[150,150],"semi_major_axis_km":[598391.4828,598391.4828],"orbital_period_days":[0.00021,0.00021]},"host_mass_solar":1.89,"inclination_deg":89.3,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":1.751,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":8500,"orbital_period_days":29.04992,"transit_midpoint_bjd":2458348.324,"eccentricity_upper_limit":0.68,"equilibrium_temperature_k":1133},"designations":[{"catalog":"Exoplanet","designation":"HD 56414 b"},{"catalog":"Host star","designation":"HD 56414"}],"source":{"id":"exoplanet_archive","name":"NASA Exoplanet Archive (Planetary Systems Composite Parameters)","url":"https://exoplanetarchive.ipac.caltech.edu/cgi-bin/TblView/nph-tblView?app=ExoTbls&config=PSCompPars","license":"Public domain (NASA)"},"updated_at":"2026-09-02T19:50:56.720Z","attribution":"Data from SpaceCatalog.org.
