CREATE TABLE table_203_56 (id DECIMAL, "star" TEXT, "start\ year" DECIMAL, "end\ year" DECIMAL, "maximum\ year" DECIMAL, "maximum\ magnitude" DECIMAL, "distance at\ maximum  ( ly ) " DECIMAL, "current\ distance" DECIMAL, "current\ magnitude" DECIMAL)

what is the difference in the nearest current distance and farthest current distance ?
SELECT MAX("current\ndistance") - MIN("current\ndistance") FROM table_203_56
SELECT MAX("current\ndistance") - MIN("current\ndistance") FROM "table_203_56"
