- A-type stars are among the more common naked eye stars, and are white or bluish-white. They have strong hydrogen lines, at a maximum by A0, and also lines of ionized metals (Fe II, Mg II, Si II) at a maximum at A5. The presence of Ca II lines is notably strengthening by this point. About 1 in 160 (0.625%) of the main-sequence stars in the solar neighborhood are A-type stars, which includes 9 stars within 15 parsecs.

Super Mario World is a 1991 video game produced by Nintendo as a launch title for their sixteen-bit console, the Super Nintendo. It features their iconic mascot Mario taking a vacation alongside his brother Luigi and Princess Peach (then still referred to in America as Princess Toadstool) to the faraway Dinosaur Land. There, as is prone to happen, Princess Peach is captured by Bowser and kept in his castle, this time located in the deep underground. Of course, Mario must journey through the entire continent to get to her, beating down Bowser’s loyal lackies/children, the seven Koopalings, along the way.
