Nakshatra (Devanagari: नक्षत्र, Sanskrit: nakshatra, 'star', from Sanskrit: naksha, 'approach', and Sanskrit: tra, 'guard') or lunar mansion is one of the 27 divisions of the sky, identified by the prominent star(s) in them, used in Jyotisha. The following are the 27 nakshatras and their meanings, with their equivalent positions in the Indian and Western zodiacs. The corresponding regions of sky are also given, following Basham's Appendix: Astronomy. Although the Indian and Western zodiac signs have a common origin, due to differences in measuring the zodiac they have diverged from each other by about 25°. Therefore in the Western zodiac 0° Aries (Mesha) corresponds to 5° Pisces (Meena) in the Indian zodiac and so on. Each nakshatra represents a division of the ecliptic similar to the zodiac (13°20' each instead of the 30° for each zodiac sign). The orbit of the moon is 27.3 days, so the Moon takes approximately one day to pass through each nakshatra.
