Both Earth and Mercury have atmospheres, but they are very different. Earth's atmosphere is dense and rich in oxygen, suitable for supporting life. Mercury has a very thin exosphere composed mainly of oxygen, sodium, hydrogen, and helium, which is not conducive to sustaining life.
Venus and Earth are the two planets that are most alike in terms of size and composition. They are similar in mass, density, and have a similar rocky composition. However, Venus has a harsh environment with extreme temperatures and a thick, toxic atmosphere, unlike Earth.
Mercury and Venus are the two inner planets most alike in size, mass, and density. They are both relatively similar in size, with Mercury being slightly smaller but denser than Venus.
They are both rocky planets
earth and venus are alike because they are both on the inner planets
Mercury's diameter is about a third that of Earth.
They both have storms such as ( lightning and swirling clods)
mercury barometers and aneroid barometers both measure air pressure.
