HD 142250 (HR 5910, HIP 77900) is a star in the constellation Scorpius. It has a visual apparent magnitude of 6.10, being visible to the naked eye only in excellent seeing conditions. From parallax measurements, it is located about 500 light-years (155 parsecs) away from Earth. This distance, together with the star's proper motion, indicate that HIP 77900 is a member of the Upper Scorpius subgroup of the Scorpius–Centaurus association, the nearest OB association to the Sun. This subgroup is the youngest of the three of the association, with an estimated age of 11 million years.

  • HD 142250 är en ensam stjärna belägen i den mellersta delen av stjärnbilden Skorpionen. Den har en skenbar magnitud av ca 6,10 och är mycket svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 6,5 mas, beräknas den befinna sig på ett avstånd på ca 500 ljusår (ca 150 parsek) från solen. Den rör sig närmare solen med en heliocentrisk radialhastighet på ca –1,3 km/s. Det beräknade avståndet, tillsammans med stjärnans egenrörelse, tyder på att stjärnan ingår i undergruppen Övre Scorpius av föreningen Scorpius – Centaurus, den närmaste OB till solen. Denna undergrupp är den yngsta av de tre i föreningen, med en beräknad ålder på 11 miljoner år. (sv)
