The Mars moon Phobos is expected to meet a similar fate. [18] Phobos gets closer to Mars by about 2 cm per year, and it is predicted that within 30 to 50 million years it will either collide with the planet or break up into a planetary ring. [19] Outside the Solar System, exomoons might collide with planets, removing life from them. [20]
American astronaut Marsha Ivins demonstrates the effects of microgravity on her hair in space. The effects of spaceflight on the human body are complex and largely harmful over both short and long term. [1] Significant adverse effects of long-term weightlessness include muscle atrophy and deterioration of the skeleton (spaceflight osteopenia). [2]
Biologists as well as artists and poets have long thought about the Moon's influence on living creatures. The lunar effect is a purported correlation between specific stages of the roughly 29.5-day lunar cycle and behavior and physiological changes in living beings on Earth, including humans. A considerable number of studies have examined the ...
This effect could be further enhanced during the portion of the Moon's orbit where it passes through Earth's magnetotail, part of the magnetic field of the Moon. [5] On the terminator there could be significant horizontal electric fields forming between the day and night areas, resulting in horizontal dust transport—a form of "Moon storm". [4 ...
Due to the potential negative effects of astronaut exposure to cosmic rays, solar activity may play a role in future space travel. Because galactic cosmic ray fluxes within the Solar System are lower during periods of strong solar activity, interplanetary travel during solar maximum should minimize the average dose to astronauts.
The Moon has been suggested as a testbed for new technology to protect sites in the Solar System, and astronauts, from forward and back contamination. Currently, the Moon has no contamination restrictions because it is considered to be "not of interest" for prebiotic chemistry and origins of life.
It is the moon with the highest volcanic activity in the Solar System, as a result of the tidal forces from the planet and its oval orbit around it. Even so, the surface is still cold: -143 Cº. The atmosphere is 200 times lighter than Earth's atmosphere, the proximity of Jupiter gives a lot of radiation, and it is completely devoid of water.
Kemadruma yoga is also caused when the Moon is in the 2nd or in the 12th house, and no planet occupies the bhavas either sides of the Moon. The Shakat yoga is caused when Jupiter occupies the 6th or the 8th house from the Moon. In both events, there will be lack of wealth and much difficulty in making a living or gaining in prosperity.
