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-707-b","name":"TOI-707 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":427.13113069407,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":98.7295889,"dec_deg":-67.5372743,"epoch_ra_deg":98.715224,"epoch_dec_deg":-67.557687,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-707","semi_major_axis_km":41139414.4425,"periapsis_km":null,"mass_kg":3.8341317711220652e+25,"mass_msun":0.0000192824,"constellation":"Volans","discovered":"2026","featured":false,"url":"https://spacecatalog.org/object/toi-707-b","radius_km":15409.4896,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-707","host_v_mag":10.71,"uncertainties":{"radius_km":[625.0538,625.0538],"distance_ly":[1.3470258399701502,1.3568105313016525],"host_mass_solar":[0.06,0.06],"inclination_deg":[0.072,0.081],"host_radius_solar":[0.021,0.021],"host_temperature_k":[61,61],"semi_major_axis_km":[1495978.707,1495978.707],"orbital_period_days":[0.00016,0.00021]},"host_mass_solar":0.99,"inclination_deg":89.602,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.978,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":5424,"orbital_period_days":52.79918,"transit_midpoint_bjd":2459295.9113,"equilibrium_temperature_k":491.7},"designations":[{"catalog":"Exoplanet","designation":"TOI-707 b"},{"catalog":"Host star","designation":"TOI-707"}],"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.
