The Moon

Below is Moon 19th of October 2011. Diameter is 3474 kilometers. Distance 384000 kilometers. Mass is only 1,2 percent of Earth mass. The surface of the Moon has stayed quite unchanged after birth of the Solar system. The dark areas are ancient lava-fields. The light areas are highlands. Asteroid impacts have created craters to the surface of the Moon. Also Earth has been impacted by the Asteroids, but erosion process has worn off most of the impact craters. The Mare Imbrium, The Sea of Rains, has diameter of 1156 kilometers. It is surrounded by 7 kilometers high mountains. Area was born 4 billion years ago when an asteroid, with 250 kilometers diameter, hit the Moon. The diameter of Archimedes crater is 83 kilometers and it is 2,1 kilometers deep. The diameter of Platon crater is 109 kilometers and it is 1 kilometers deep.

In the image below the landing sites of the manned Apollo missions are marked. Apollo 11 was year 1969 and Apollo 17 year 1972.

The Moon 8th and 6th of February 2017. Celestron 8 F10. Exposures 1/800s, ISO1600, Canon Eos 60Da. Stacked 30 images with RegiStax software.

The Apollo 11 landed on Moon 20th of July 1969. First man on the moon was Niel Armstrong, with the famous first words on the moon: "One small step for man, one giant leap for mankind". Apollo 17 in 1972 was the last manned mission to Moon. Apollo 13, year 1970, had an accident and it did not land on Moon: "Houston, We've Got a Problem". In image below is also image of Niel and Barry DiGregorio , who has studied microbial level life on Mars planet.

Phases of the Moon in 3 subsequent nights and development of scenery around Theophilus crater when the Sun is rising higher on the sky of the Moon. Daytime temperature on Moon is +123 C and on nigth -233 C. Moon goes around Earth in 27,3 days, so the day on Moon is 13,6 Earth days.

The diameter of Tycho crater is 85 kilometers and it is 4.6 kilometers deep. It is young, only 108 million years old. There goes rays from the Tycho crater around the moon, even to 1500 kilometers distance. The crater is named according to astronomer Tycho Brahe. The diameter of Clavius crater is 225 kilometers and it is 3.5 kilometers deep. It was born 4 billion years ago. The diameter of Copernicus crater is 96 kilometers and it is 3.8 kilometers deep. It was born 800 million years ago. The crater is named according to astronomer Nikolaus Kopernikus.

Rupes Recta is 110 kilometers long straigth wall. Hight 240-300 meters and 2-3 kilometers wide.The diameter of Ptolemaeus crater is 153 kilometers and it is 2,4 kilometers deep.

Hyginus crater and Hyginus Rille is probably a volcanic formation.

The diameter of Theophilus crater is 100 kilometers and the depth is 3,2 kilometers.

The diameter of Posidonius crater is 95 kilometers and it is 2,3 kilometers deep.

The diameter of Mare Crisium is 570 kilometers. The diameter of Langrenus crater is 132 kilometers and it is 2,7 kilometers deep.

Total eclipse of the Moon 21st of January 2019 at Kirkkonummi, Finland. Temperature was -19 C. The red color is caused by red end sun ligth which gets trough and bends in earth atmosphere, hitting the moon. Telescope SkyWatcher 80/600 ED and camera Canon Eos 60Da.

Moon moving to Earth shadow. First touch to full shadow at 05:37. In full shadow 06:42. Deepest 07:13. First images are with 1/1600 second exposures. Last images are with 1000 times longer exposures, 1-2 seconds. Camera sensitivity set to ISO 1600.

Moon and it's details 15th of April 2019. The small images are stacks of 60 videoframes with Registax software. Copernikus crater has diameter of 93 kilometers and depth 3.8 kilometers. Tycho crater has diameter of 85 kilometers and depth 4.6 kilometers. It is young crater, 108 million years. We can still see the materia rays on surface of moon from the impact. Cassendi crater has diameter of 110 kilometers and depth 1.9 kilometers.
