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":"ic-1295","name":"IC 1295","class":"planetary_nebula","category":"nebula","object_type":"Planetary nebula","mag":12.5,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":3372.456945591127,"distance_method":"Statistical distance scale for planetary nebulae (Stanghellini+ 2008)","ra_deg":283.6547083333333,"dec_deg":-8.827027777777777,"epoch_ra_deg":284.02123,"epoch_dec_deg":-8.79353,"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":"Scutum","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/ic-1295","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":15,"v_mag":12.5,"redshift":-0.000043,"wikidata_id":"Q1653282","ngc_type_code":"PN","major_axis_arcmin":1.5,"wikipedia_article":"IC 1295","distance_reference":"IC 1295","radial_velocity_km_s":-13},"designations":[{"catalog":"IC","designation":"IC 1295"},{"catalog":"IRAS","designation":"IRAS 18519-0853"},{"catalog":"PK","designation":"PK 25-04 2"},{"catalog":"PN","designation":"PN G025.4-04.7"}],"source":{"id":"openngc","name":"OpenNGC","url":"https://github.com/mattiaverga/OpenNGC","license":"CC-BY-SA-4.0"},"updated_at":"2026-08-27T19:16:43.430Z","attribution":"Data from SpaceCatalog.org.
