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":"kepler-395-c","name":"Kepler-395 c","class":"super_earth","category":"exoplanet","object_type":"Super-Earth","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":1374.3642675503677,"distance_method":"NASA Exoplanet Archive sy_dist (TICv8, 2019AJ....158..138S)","ra_deg":293.5111889,"dec_deg":45.1366252,"epoch_ra_deg":293.716567,"epoch_dec_deg":45.194412,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":"Kepler-395","semi_major_axis_km":26478823.113899995,"periapsis_km":null,"mass_kg":1.3735986095920172e+25,"mass_msun":0.00000690803,"constellation":"Cygnus","discovered":"2014","featured":false,"url":"https://spacecatalog.org/object/kepler-395-c","radius_km":8419.092,"radius_kind":null,"data_quality":null,"description":null,"properties":{"host_star":"Kepler-395","host_v_mag":16.5919,"eccentricity":0,"uncertainties":{"radius_km":[574.029,574.029],"distance_ly":[26.38768173917313,26.38768173917313],"host_mass_solar":[0.021315,0.021315],"inclination_deg":[0.077,0.0023],"host_radius_solar":[0.022,0.022],"host_temperature_k":[100,100],"orbital_period_days":[0.000543,0.000543]},"host_mass_solar":0.622827,"inclination_deg":89.96,"stars_in_system":1,"discovery_method":"Transit","host_radius_solar":0.556,"planets_in_system":2,"discovery_facility":"Kepler","host_temperature_k":4262,"orbital_period_days":34.989262,"transit_midpoint_bjd":2454977.22265,"equilibrium_temperature_k":341},"designations":[{"catalog":"Exoplanet","designation":"Kepler-395 c"},{"catalog":"Host star","designation":"Kepler-395"}],"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.
