Mayan astronomers discover an 18.7-year cycle in the rising and setting of the Moon. From this they created the first almanacs – tables of the movements of the Sun, Moon, and planets for the use in astrology. In 6th century BC Greece, this was also discovered
NASA probe that will complete a 12-year journey to nine different asteroids, visiting two main belt asteroids as well as six Jupiter trojans, [26] [27] asteroids which share Jupiter's orbit around the Sun, orbiting either ahead of or behind the planet. All target encounters will be fly-by encounters. [28]
