The classic Metonic cycle can be reproduced by assigning an initial epact value of 1 to the last year of the cycle and incrementing by 11 each year. Between the last year of one cycle and the first year of the next the increment is 12 – the saltus lunae (Latin for 'leap of the moon') – which causes the epacts to repeat every 19 years. When ...
Since the period of 12 such lunations, a lunar year, is 354 days, 8 hours, 48 minutes, 34 seconds (354.36707 days), [1] purely lunar calendars are 11 to 12 days shorter than the solar year. In purely lunar calendars, which do not make use of intercalation, the lunar months cycle through all the seasons of a solar year over the course of a 33 ...
China's standard satellite telemetry had a range of 80,000 kilometers (50,000 miles), but the distance between the Moon and the Earth can exceed 400,000 kilometers (250,000 miles) when the Moon is at apogee. In addition, the Chang'e probes had to carry out many attitude maneuvers during their flights to the Moon and during operations in lunar ...
On 20 July 1969 Apollo 11 landed on the Moon, and Neil Armstrong became the first person to walk on the Moon. At the same time another mission, the robotic sample return mission Luna 15 by the Soviet Union, was in orbit around the Moon, becoming together with Apollo 11 the first ever case of two extraterrestrial missions being conducted at the ...
Chang'e 5 (Chinese: 嫦娥五号; pinyin: Cháng'é wǔhào [note 1]) was the fifth lunar exploration mission in the Chinese Lunar Exploration Program of CNSA, and China's first lunar sample-return mission. [13] Like its predecessors, the spacecraft is named after the Chinese moon goddess, Chang'e.
[21] [2] In more than 96 per cent of years, the Chinese New Year is the closest new moon to the beginning of spring according to the calendar. In the Gregorian calendar, the Chinese New Year occurs on the new moon that falls between 21 January and 20 February. [22]
Chinese New Year usually falls on the second new moon after the winter solstice (rarely the third if an intercalary month intervenes). [5] Some Lunar New Year celebrations, such as in Korea and Vietnam, generally fall on the same day as the Chinese celebration in late January or February, due to being based on the Chinese calendar or a ...
