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":"toi-712-d","name":"TOI-712 d","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":191.19678249408759,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":92.9361063,"dec_deg":-65.8258386,"epoch_ra_deg":92.947264,"epoch_dec_deg":-65.831222,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-712","semi_major_axis_km":50938074.97335,"periapsis_km":null,"mass_kg":3.989408135684641e+25,"mass_msun":0.0000200633,"constellation":"Dorado","discovered":"2022","featured":false,"url":"https://spacecatalog.org/object/toi-712-d","radius_km":15779.419400000002,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-712","host_v_mag":10.838,"eccentricity":0.073,"uncertainties":{"radius_km":[523.0042000000001,574.029],"distance_ly":[0.25929432028481103,0.25994663304024446],"eccentricity":[0.049,0.064],"host_mass_solar":[0.025,0.027],"inclination_deg":[0.066,0.11],"host_radius_solar":[0.016,0.017],"host_temperature_k":[59,61],"semi_major_axis_km":[583431.6957299999,613351.26987],"orbital_period_days":[0.0004,0.00043],"argument_of_periastron_deg":[140,110]},"host_mass_solar":0.732,"inclination_deg":89.817,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.674,"planets_in_system":3,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_spectral_type":"K4.5 V","host_temperature_k":4622,"orbital_period_days":84.8396,"periastron_epoch_bjd":2458396,"transit_midpoint_bjd":2458640.5457,"equilibrium_temperature_k":313.6,"argument_of_periastron_deg":30},"designations":[{"catalog":"Exoplanet","designation":"TOI-712 d"}],"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.
