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":"epic-201595106-b","name":"EPIC 201595106 b","class":"super_earth","category":"exoplanet","object_type":"Super-Earth","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":757.0089526805615,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":183.7203635,"dec_deg":1.9681688,"epoch_ra_deg":184.064322,"epoch_dec_deg":1.818795,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"EPIC 201595106","semi_major_axis_km":2647882.31139,"periapsis_km":null,"mass_kg":4.580652754595988e+25,"mass_msun":0.0000230368,"constellation":"Virgo","discovered":"2021","featured":false,"url":"https://spacecatalog.org/object/epic-201595106-b","radius_km":9981.7265,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"EPIC 201595106","host_v_mag":11.746,"eccentricity":0,"uncertainties":{"mass_kg":[4.4791259008435344e+24,4.4791259008435344e+24],"radius_km":[503.86990000000003,503.86990000000003],"distance_ly":[8.63009775438503,8.825791581015077],"host_mass_solar":[0.048,0.048],"inclination_deg":[0.7,0.7],"host_radius_solar":[0.025,0.025],"host_temperature_k":[39,60],"semi_major_axis_km":[44879.361209999995,44879.361209999995],"orbital_period_days":[0.00004,0.00004]},"host_mass_solar":0.958,"inclination_deg":78.2,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.98,"planets_in_system":2,"discovery_facility":"K2","host_temperature_k":5679,"orbital_period_days":0.87724,"periastron_epoch_bjd":2458204.2649,"transit_midpoint_bjd":2457583.04429,"equilibrium_temperature_k":2038,"argument_of_periastron_deg":0},"designations":[{"catalog":"Exoplanet","designation":"EPIC 201595106 b"}],"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.
