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-2107-b","name":"TOI-2107 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":772.0284538744176,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":286.7965405,"dec_deg":-58.6968348,"epoch_ra_deg":287.376646,"epoch_dec_deg":-58.655087,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-2107","semi_major_axis_km":5258365.155104999,"periapsis_km":null,"mass_kg":1.5754434177980783e+27,"mass_msun":0.000792313,"constellation":"Pavo","discovered":"2024","featured":false,"url":"https://spacecatalog.org/object/toi-2107-b","radius_km":86576.811775703,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-2107","host_v_mag":12.0363,"eccentricity":0.033,"uncertainties":{"mass_kg":[2.0879370597323927e+26,2.0879370597323927e+26],"radius_km":[2287.743978378,2502.2199643920003],"distance_ly":[6.210017431726794,6.307864345041818],"eccentricity":[0.023,0.038],"host_mass_solar":[0.054,0.049],"inclination_deg":[0.58,0.39],"host_radius_solar":[0.024,0.027],"host_temperature_k":[93,94],"semi_major_axis_km":[100230.57336899999,88262.743713],"orbital_period_days":[0.0000013,0.0000013],"argument_of_periastron_deg":[97,100]},"host_mass_solar":0.961,"inclination_deg":89.44,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.932,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":5627,"orbital_period_days":2.4545467,"transit_midpoint_bjd":2459228.98176,"equilibrium_temperature_k":1397,"argument_of_periastron_deg":153},"designations":[{"catalog":"Exoplanet","designation":"TOI-2107 b"},{"catalog":"Host star","designation":"TOI-2107"}],"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.
