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-2295-c","name":"TOI-2295 c","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":411.8670122169264,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":281.5761962,"dec_deg":50.4924657,"epoch_ra_deg":281.742157,"epoch_dec_deg":50.520427,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TOI-2295","semi_major_axis_km":301888503.07259995,"periapsis_km":null,"mass_kg":1.0648479004635203e+28,"mass_msun":0.00535527,"constellation":"Draco","discovered":"2024","featured":false,"url":"https://spacecatalog.org/object/toi-2295-c","radius_km":81639.68000000001,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TOI-2295","host_v_mag":9.595,"eccentricity":0.194,"uncertainties":{"mass_kg":[4.5554990394161295e+26,4.365686579440458e+26],"distance_ly":[1.2850561282039692,1.291579255758304],"eccentricity":[0.012,0.012],"host_mass_solar":[0.071,0.07],"host_radius_solar":[0.058,0.056],"host_temperature_k":[140,140],"semi_major_axis_km":[6283110.569399999,5983914.828],"orbital_period_days":[4.2,4.3],"argument_of_periastron_deg":[3,3]},"host_mass_solar":1.168,"stars_in_system":1,"discovery_method":"Radial Velocity","host_radius_solar":1.459,"planets_in_system":2,"discovery_facility":"Haute-Provence Observatory","host_temperature_k":5730,"orbital_period_days":966.5,"transit_midpoint_bjd":2459302.8,"equilibrium_temperature_k":234.9,"argument_of_periastron_deg":39.5},"designations":[{"catalog":"Exoplanet","designation":"TOI-2295 c"}],"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.
