Atmosphere

Today in our Science class talk about Atmosphere  and focusing about the planet mercury.
Mercury is the  smallest and least massive of the eight planets. Its low surface gravity makes holding on to an atmosphere in the best of circumstances a challenge.Mercury has the thinnest atmosphere, thinner than even Mars the mercury near to the sun  Mercury hold on to its atmosphere is its magnetic field. While gravity helps hold the gases to the surface, the magnetic filed helps to deflect the solar wind around the planet, much like it does here on Earth. This deflection allows a smaller gravitational pull to hold some form of an atmosphere.the mercury near to the sun

The two reasons Mercury lost most of its atmosphere?
       The mercury near to the sun and it's small that cause the atmosphere blew away.

Compare how close mercury & earth are to  the sun?
                          Two time farther to sun.

 Compare how much mass mercury & Earth have?
mercury mass is approximately 3.3 times 10 23 kg (5.5% the mass of earth.
