# MOON


Moon is the only natural satellite of the Earth. [8] It is the fifth largest solar satellite of the Solar System. Distance from the middle of the moon to the middle of the moon is 384,403 kilometers. This distance is 30 times the circumference of the Earth. Gravity is 1/6 of the Earth on the Moon. This earth completes orbits in 27.3 days and also places a full circle around its axis in 27.3 days. This is the reason that only one part of the moon or face is always towards the Earth. If you stand on the moon and see the earth, the earth will be clearly rotating on its axis, but its position in the sky will remain steadfast, meaning that the Earth will remain silent for many years. Due to Earth-Moon-Sun Geometry, "Chandra Dasha" varies in every 9.5 days. According to the size of the planet, it is the largest natural satellite in the solar system whose diameter is one fourth of the Earth and the mass is 1/81. Moon is the second most dense satellite after Jupiter's satellite lo. After the sun, the brightest body in the sky is the moon. Marine tides and reflux are due to the moon's gravitational power. The instantaneous orbital distance of the moon is 30 times the diameter of the Earth, therefore, the size of the sun and the moon are always visible in the sky. He sees 59% of the moon from Pathvi when the Moon passes through the Sun and Earth rotating in its orbit and covers the Sun completely, then it is called Solar Eclipse.

In space, humans can only move on the Moon. The Luna-1 of the Soviet nation was the first spacecraft to pass through the Moon, but Luna-II was the first vehicle that landed on the moon's land. In 1968 only the NASA Apollo program had achieved the achievement of sending human missions at that time and the first manned 'Chandra Parikrama Mission' was started with Apollo-8. Between 1969 and 1972, six manned ships took to the moon land, from which Apollo-11 first stepped. During these withdrawals, 380 km G More than the Moon returned with the rocks used to develop the detailed geological understanding of the origin of the Moon, the formation of its internal structure and subsequent history. It is believed that about 4.5 billion years ago, a massive collision with the Earth has formed it.![FullMoon2010.jpg](https://steemitimages.com/DQmbhfe5Jkaus7HXFrfF8KL3fu5CmCLBJVvsWkkQfzmAAv1/FullMoon2010.jpg)

Since the Apollo -17 mission in 1972, the Moon was visited only by unmanned spacecraft, especially by the last Soviet Lunokhod Rover. Since 2004, each of Japan, China, India, the United States and the European Space Agency has sent the yacht to the moon revolution. These space missions have made a special contribution to confirm the discovery of water-ice on the Moon. The future manmade mission scheme for the Moon has been created with the government as well as personal funded efforts. The Moon lives under 'Outer Space Convention', which is free for all nations to discover peaceful objectives.![Back_side_of_the_Moon_AS16-3021.jpg](https://steemitimages.com/DQmdbpw6SiaqAyWv4Pvx6s1PVHnoZcqhzSMohSMo6mse83h/Back_side_of_the_Moon_AS16-3021.jpg)

Chandrayaan (or Chandrayaan-1) was India's first [9] spacecraft to fly towards the moon, under the lunar exploration program of the Indian Space Research Organization.![moon-stock-image.jpg](https://steemitimages.com/DQmYfPH7r79PL4afpdJgDjyUtDoNGtnWRxDaFXetLH9GiG1/moon-stock-image.jpg)
