  • WR 102 (auch: Sand 4) ist ein Wolf-Rayet-Stern im Sternbild Schütze der sehr seltenen Spektralklasse WO. Seine Oberfläche hat eine extrem hohe Temperatur von rund 200.000 Kelvin und er steht in seiner Entwicklung kurz vor seinem Ende als Supernova. Der Stern ist von einem Nebel mit der Bezeichnung G2.4+1.4 umgeben. (de)
  • WR 102 est une étoile Wolf-Rayet de la constellation du sagittaire, à proximité du centre de notre galaxie à environ 8 500 années-lumière (2 600 parsec). Ce type d'étoile est extrêmement rare. Cette étoile est de type spectral WO (les raies de son spectre proviennent majoritairement d'oxygène). (fr)

  • WR 102 – gwiazda Wolfa-Rayeta w gwiazdozbiorze Strzelca, niezwykle rzadka gwiazda o typie widmowym WO. Jest jasną i bardzo gorącą gwiazdą, wysoko rozwiniętą i bliską eksplozji jako supernowa. (pl)
  • WR 102 è una stella di Wolf-Rayet nella costellazione del Sagittario distante circa 9400 anni luce dal sistema solare. Si tratta di una stella di classe WO2, vale a dire che presenta nel proprio spettro le linee dell'O V-VI (ossigeno ionizzato quattro o cinque volte), una classe molto rara a cui fino ad oggi sono state attribuite solo quattro stelle della Via Lattea. Si ritiene che WR 102 – al momento della sua scoperta la stella più calda conosciuta – si trovi in uno stadio molto avanzato della sua storia evolutiva e che sia prossima ad esplodere in una supernova.
