Hoshi Stars星

The stars you can see without a telescope, with names, colours and distances; the 88 constellations with their lines and boundaries; the Messier objects; and seven map projections to draw them on.

Hoshi is the Japanese word 星 for a star. About the name

Contents

Reference · The Messier objects

deepSkyObjectfunction

A Messier object by any of its names, ignoring case, spacing and the accent on a letter: the Messier designation (M31, m 31, Messier 31), its NGC or IC designation (NGC 224, ngc224) or its common name in English (Andromeda Galaxy, Andromeda Nebula). A name that two objects share finds neither, except that a Messier object keeps its name.
