Luna (ali Luna) je edini naravni satelit Zemlje in je nastal pred 4,6 milijardami let približno približno 30-50 milijonov let po nastanku sončnega sistema. Luna se sinhrono vrti z Zemljo, kar pomeni, da je ista stran vedno obrnjena proti Zemlji. Prvo misijo brez posadke na Luno je leta 1959 opravil sovjetski Lunin program, prvi pristanek s človeško posadko pa je bil Apollo 11 leta 1969.

PODROBNA LUČNA DEJSTVA
- Temna stran lune je mit.
In reality both sides of the Moon see the same amount of sunlight however only one face of the Moon is ever seen from Earth. This is because the Moon rotates around on its own axis in exactly the same time it takes to orbit the Earth, meaning the same side is always facing the Earth. The side facing away from Earth has only been seen by the human eye from spacecraft. - Vzpon in padec plime in oseke na Zemlji povzroča Luna.
There are two bulges in the Earth due to the gravitational pull that the Moon exerts; one on the side facing the Moon, and the other on the opposite side that faces away from the Moon, The bulges move around the oceans as the Earth rotates, causing high and low tides around the globe. - Luna se oddaljuje od Zemlje.
Luna se vsako leto odmakne približno 3,8 cm od našega planeta. Ocenjuje se, da bo to počel približno 50 milijard let. Ko se bo to zgodilo, bo Luni treba okoli 47 dni, da obkroži Zemljo, namesto sedanjih 27,3 dni. - Človek bi na Luni tehtal veliko manj.
The Moon has much weaker gravity than Earth, due to its smaller mass, so you would weigh about one sixth (16.5%) of your weight on Earth. This is why the lunar astronauts could leap and bound so high in the air. - Po Luni je hodilo le 12 ljudi; vsi ameriški moški.
Prvi človek, ki je stopil na Luno leta 1969, je bil Neil Armstrong v misiji Apollo 11, zadnji človek, ki je hodil po Luni leta 1972, pa je bil Gene Cernan v misiji Apollo 17. Od takrat Luno obiskujejo le vozila brez posadke. - Luna nima vzdušja.
This means that the surface of the Moon is unprotected from cosmic rays, meteorites and solar winds, and has huge temperature variations. The lack of atmosphere means no sound can be heard on the Moon, and the sky always appears black. - Luna ima potrese.
These are caused by the gravitational pull of the Earth. Lunar astronauts used seismographs on their visits to the Moon, and found that small moonquakes occurred several kilometres beneath the surface, causing ruptures and cracks. Scientists think the Moon has a molten core, just like Earth. - Prvo vesoljsko plovilo, ki je doseglo Luno, je bila Luna 1 leta 1959.
To je bilo sovjetsko plovilo, ki se je začelo iz ZSSR. Prešel je v 5995 km od površine Lune, preden je šel v orbito okoli Sonce. - Luna je peti največji naravni satelit v Osončju.
At 3,475 km in diameter, the Moon is much smaller than the major moons of Jupiter in Saturn. Earth is about 80 times the volume than the Moon, but both are about the same age. A prevailing theory is that the Moon was once part of the Earth, and was formed from a chunk that broke away due to a huge object colliding with Earth when it was relatively young. - Luno bo v bližnji prihodnosti obiskal človek.
NASA namerava astronavte vrniti na Luno, da bi postavili stalno vesoljsko postajo. Človeštvo bo lahko spet hodilo po Luni leta 2019, če bo šlo vse po načrtih. - V petdesetih letih so ZDA razmišljale o eksploziji jedrske bombe na Luni.
Tajni projekt je bil v času hladne vojne v višini znan kot "Študija lunarnih raziskovalnih letov" ali "Projekt A119" in je bil mišljen kot pokaz moči v času, ko so zaostajali v vesoljski tekmi.
