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":"psr-j1914p0219","name":"PSR J1914+0219","class":"pulsar","category":"neutron_star","object_type":"Pulsar","mag":null,"mag_band":null,"abs_mag":null,"abs_mag_band":null,"distance_ly":46692.54703392899,"distance_method":"dispersion measure through the YMW16 electron-density model","ra_deg":288.59914166666664,"dec_deg":2.329939472222222,"epoch_ra_deg":288.937608,"epoch_dec_deg":2.375874,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Aquila","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/psr-j1914p0219","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"spin_period_s":0.4575271458212469,"spin_period_derivative":1.0181236183637197e-15,"radio_flux_1400_mhz_mjy":1.6,"characteristic_age_years":7120039.31182073,"dispersion_measure_pc_cm3":235.425,"spin_down_luminosity_erg_s":4.196716663831152e+32,"surface_magnetic_field_gauss":690651036225.9863},"designations":[{"catalog":"ATNF","designation":"J1914+0219"},{"catalog":"ATNF","designation":"PSR J1914+0219"}],"source":{"id":"atnf","name":"ATNF Pulsar Catalogue (Manchester+ 2005)","url":"https://www.atnf.csiro.au/research/pulsar/psrcat","license":"Free to use with attribution; cite Manchester+ 2005 (2005AJ....129.1993M)"},"updated_at":"2026-09-02T19:50:56.720Z","attribution":"Data from SpaceCatalog.org.
