SATELLITE CAUSE THE LIGHT POLLUTION

   Light pollution causes due to the excessive light during night time. This light reflection will reduce the darkness of the night sky .Today 90% of stars which can be seen with naked eye are invisible. Doctors have proved that this light pollution will affect the health of human. The production of melanin occurs in darkness of night will affected by brightness of light . Also affect the eyesight of human by LED light. 


   Most of the nocturnal animal will distracted from moonlight or confused by manmade light. Some of the birds use dark as their orient to migrate which were fail due the high intensity of light in urban areas. Due to the light the day time get into the night and night time will reduced. Thus it leads to habitat changes in the ecosystem and leads to extinction of nocturnal animals.


   In lake, when the natural night light is reduced then zooplankton will not eat the algae. This leads to increase in the growth of bacteria which reduce the oxygen level in lake. Thus affect the water ecosystem. The glow in the sky the image of dim object will be foggy and unclear. This affect the astronomer study at fluorescent object such as their chemical composition ,temperature and speed at which they move. Astronomer often attempt to takes spectra of object and fail to do so.
   Number of objects are orbit the earth will increase the brightness of the night sky by more than 10%. We can see the satellite in sky for few minutes while they revolve the earth that looks like star in the sky. If the object move with blinking light it is plane while the satellite will not produce light of its own . Light formation on satellite due to sunlight reflection as solar rays will power the satellites. Highly reflective solar panel making it brightest. To overcome this light pollution the mega consolation satellites are developed.
