1.What are two reasons mercury lost most of its atmosphere?
However, for reasons that are still poorly understood, the Martian atmosphere thinned. The leading theory is that Mars' light gravity, coupled with its lack of global magnetic field, left the atmosphere vulnerable to pressure from the solar wind, the constant stream of particles coming from the sun.
2 compare how close mercury and the earth are to the sun?
At an average distance of only 57.9 million km, Mercury orbits closer to the Sun than any other planet.
3 compare how much mass mercury and the earth have?
For comparison, the eccentricity of the Earth's much more circular orbit is only 0.0167. Mercury, as the innermost planet, is also the fastest moving major planet in the solar system
4 How does not having an atmosphere affect the temperature on mercury?
On the Earth and other planets with an atmosphere, so-called greenhouse gases can trap part of the heat radiated by the surface, keeping the surface warmer.
