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":"tic-365102760-b","name":"TIC 365102760 b","class":"gas_giant","category":"exoplanet","object_type":"Gas giant","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":1811.9487101502596,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":305.8398236,"dec_deg":54.3943194,"epoch_ra_deg":306.012781,"epoch_dec_deg":54.480221,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"TIC 365102760","semi_major_axis_km":9304987.55754,"periapsis_km":null,"mass_kg":1.1466562306159448e+26,"mass_msun":0.000057667,"constellation":"Cygnus","discovered":"2024","featured":false,"url":"https://spacecatalog.org/object/tic-365102760-b","radius_km":39608.001000000004,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"TIC 365102760","host_v_mag":12.154,"uncertainties":{"mass_kg":[2.5083105044723793e+25,2.5083105044723793e+25],"radius_km":[4847.356000000001,4847.356000000001],"distance_ly":[24.44215894609275,25.110779520412077],"host_mass_solar":[0.12,0.12],"host_radius_solar":[0.12,0.12],"host_temperature_k":[90,90],"semi_major_axis_km":[733029.5664299999,733029.5664299999],"orbital_period_days":[7.4e-7,7.4e-7],"argument_of_periastron_deg":[1.698,1.698]},"host_mass_solar":1.17,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":3.13,"planets_in_system":1,"discovery_facility":"Transiting Exoplanet Survey Satellite (TESS)","host_temperature_k":4900,"orbital_period_days":4.21285367,"transit_midpoint_bjd":2458684.146,"eccentricity_upper_limit":0.406,"equilibrium_temperature_k":1676.12,"argument_of_periastron_deg":0.216},"designations":[{"catalog":"Exoplanet","designation":"TIC 365102760 b"},{"catalog":"Host star","designation":"TIC 365102760"}],"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.
