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-97037-b","name":"HD 97037 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":105.71706670932804,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":167.5545621,"dec_deg":-7.3901483,"epoch_ra_deg":167.894369,"epoch_dec_deg":-7.535823,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"HD 97037","semi_major_axis_km":1035965254.5974998,"periapsis_km":null,"mass_kg":4.005991967783573e+28,"mass_msun":0.0201467,"constellation":"Crater","discovered":"2022","featured":false,"url":"https://spacecatalog.org/object/hd-97037-b","radius_km":77175.01000000001,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"HD 97037","host_v_mag":6.81828,"eccentricity":0.357,"uncertainties":{"mass_kg":[3.9291179214964116e+27,3.7203242155231725e+27],"distance_ly":[0.18656144805397723,0.18753991718712748],"eccentricity":[0.03,0.027],"host_mass_solar":[0.129,0.129],"inclination_deg":[0.713,0.798],"host_radius_solar":[0.068454,0.056068],"host_temperature_k":[118.16,136.84],"semi_major_axis_km":[47572122.882599995,42336197.408099994],"orbital_period_days":[153.98638,141.956],"argument_of_periastron_deg":[1.955,2.336]},"host_mass_solar":1.06,"inclination_deg":14.561,"stars_in_system":1,"discovery_method":"Radial Velocity","host_radius_solar":1.26356,"planets_in_system":1,"discovery_facility":"Multiple Observatories","host_temperature_k":5874.1,"orbital_period_days":6449.08337,"periastron_epoch_bjd":2445839.855,"equilibrium_temperature_k":120.99,"argument_of_periastron_deg":109.386},"designations":[{"catalog":"Exoplanet","designation":"HD 97037 b"},{"catalog":"Host star","designation":"HD 97037"}],"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.
