Vytautas Straižys (born August 20, 1936)[1] is a Lithuanian astronomer. In 1963-1965 he and his collaborators created and developed the Vilnius photometric system - a seven color intermediate band system, optimized for photometric stellar classification. In 1996 he was elected a Corresponding Member of the Lithuanian Academy of Sciences.[1] Straižys is an editor of the journal Baltic Astronomy. He is currently working at the Molėtai Astronomical Observatory. Asteroid 68730 Straizys in 2002 was named after him.
