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":"ngc-2762","name":"NGC 2762","class":"lenticular_galaxy_s0","category":"galaxy","object_type":"Lenticular galaxy S0","mag":15.86,"mag_band":"B","abs_mag":null,"abs_mag_band":null,"distance_ly":229161475.9828613,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":137.47720833333332,"dec_deg":50.41825,"epoch_ra_deg":137.944914,"epoch_dec_deg":50.309161,"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":"Ursa Major","discovered":"1851","featured":false,"url":"https://spacecatalog.org/object/ngc-2762","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":15.86,"h_mag":12.56,"j_mag":13.06,"k_mag":12.41,"redshift":0.01564,"hubble_type":"S0","wikidata_id":"Q1050750","redshift_cmb":0.01620630098249176,"discovered_by":"William Parsons, 3rd Earl of Rosse","ngc_type_code":"G","uncertainties":{"distance_ly":[16895347.911638383,16895347.911638383]},"major_axis_arcmin":0.51,"minor_axis_arcmin":0.36,"position_angle_deg":180,"surface_brightness":23.17,"radial_velocity_km_s":4652},"designations":[{"catalog":"2MASX","designation":"2MASX J09095451+5025059"},{"catalog":"LEDA","designation":"LEDA 25828"},{"catalog":"MCG","designation":"MCG +08-17-045"},{"catalog":"NGC","designation":"NGC 2762"},{"catalog":"PGC","designation":"PGC 25828"},{"catalog":"SDSS","designation":"SDSS J090954.52+502505.9"},{"catalog":"SDSS","designation":"SDSS J090954.53+502505.7"},{"catalog":"SDSS","designation":"SDSS J090954.54+502505.7"}],"source":{"id":"openngc","name":"OpenNGC","url":"https://github.com/mattiaverga/OpenNGC","license":"CC-BY-SA-4.0"},"updated_at":"2026-09-02T19:50:56.720Z","attribution":"Data from SpaceCatalog.org.
