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":"bd-03-2562-b","name":"BD+03 2562 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":3491.92802674877,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":177.5647268,"dec_deg":2.7601075,"epoch_ra_deg":177.909338,"epoch_dec_deg":2.610748,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"BD+03 2562","semi_major_axis_km":194477231.91,"periapsis_km":null,"mass_kg":1.214805832588886e+28,"mass_msun":0.00610943,"constellation":"Virgo","discovered":"2017","featured":false,"url":"https://spacecatalog.org/object/bd-03-2562-b","radius_km":81001.87,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"BD+03 2562","host_v_mag":9.577,"eccentricity":0.2,"uncertainties":{"mass_kg":[2.4675743474461742e+27,2.4675743474461742e+27],"distance_ly":[208.33238626656987,208.33238626656987],"eccentricity":[0.08,0.12],"host_mass_solar":[0.25,0.25],"host_radius_solar":[8.82,8.82],"host_temperature_k":[20,20],"semi_major_axis_km":[14959787.07,14959787.07],"orbital_period_days":[2.8,2.7],"argument_of_periastron_deg":[26,32]},"host_mass_solar":1.14,"stars_in_system":1,"discovery_method":"Radial Velocity","host_radius_solar":32.35,"planets_in_system":1,"discovery_facility":"Multiple Observatories","host_temperature_k":4095,"orbital_period_days":481.9,"periastron_epoch_bjd":2453726,"equilibrium_temperature_k":985.04,"argument_of_periastron_deg":218},"designations":[{"catalog":"Exoplanet","designation":"BD+03 2562 b"},{"catalog":"Host star","designation":"BD+03 2562"}],"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.
